The phrase "common sense" carries the implication that the knowledge is widespread, and possessed by fairly everyone. However, anyone who has spent a moderate amount of time on this planet will tell you there are quite a few "uncommon" people who seem to lack some of the most basic understanding of human interactions. I felt that it was time to impart some basic "common sense" to those who apparently don't know these things:
1) Never slap your money down on a counter. It doesn't matter if you lay each coin gently down or sling a wad of bills at the cashier, both communicate "You are beneath me and must pick up what I drop." Oddly enough, the person who counts out each nickle will also hold out her hand to receive the three cents owed back to her. Cashiers are people; hand them your money.
2) I am not the fashion police, and frankly people who are bore me. Having said that, unless you actually want people to know that you proudly wear a specific brand of underwear, don't tuck your shirt into them. They will ride up. Besides, Fruit of the Loom is not a brand you should be proudly broadcasting up past your bellybutton.
3) On that note grandmotherly ladies, unless you are intentionally meaning to look mentally unbalanced and a tad scary, don't wear your hair in two long, "piggy tails," or side "pony tails," or whatever they are called. As I mentioned, I don't know much about fashion or care, but if you are mature and still dressing like a child, the effect is startling.
4) To avoid looking like jerk, simply acknowledge store greeters. You don't have to carry on a conversation, you don't have to become best friends, you don't even need to give them money to buy cigarets and food. A smile would work, or even just a nod! It's simple really.
5) Items that are not scanning properly are never free. Let me repeat that. Items that are not scanning properly are NEVER FREE. While this might not be technically "common sense" sort of knowledge, let me just inform the general public that joke is tired and ragged to every cashier on the planet. Now you know.
6) If a company suddenly enters into the political spotlight for expressing a controversial opinion, charging into the nearest location to express your criticism OR support isn't likely to have any affect. You need to contact the corporate headquarters. It is quite possible the employees do not share your opinion but cannot express themselves while on the clock, making for an awkward exchange.
7) Employees at most store locations do not purchase, supply, or create the product on display. If there is a problem, their job is to work with you to the best of their ability. They cannot make you a new item, start carrying a something new just because you asked them to, or randomly change our product because it doesn't please you. Again, contact the corporate offices. Their buyers might be interested in your suggestions.
8) Talking on the phone while trying to conduct business is rude. Having said that, some people are clearly so self absorbed and obnoxious many cashiers are glad they are talking on the phone so that they don't actually have to interact with them. Also, it is rude to talk on the phone, putting a person on speaker phone while you walk through the store so everyone can hear your whole conversation is disturbing. No thank you.
9) Not all nurses, flight attendants, librarians or cashiers are female. I cannot tell you how many times I have been called "Ma'am" in spite of my shaved head and facial hair. Odd. Maybe it is my man boobs.
10) Shopping carts are not trashcans. Some of you will find this shocking, but employees aren't actually planning on cleaning out your left over coffee cups, chicken nuggets, crumpled-up used tissues, or soiled diapers. We only do it because we don't want those items cluttering up our place of business. If you cannot find the trashcan's that most stores have conveniently located right outside their doors or in the restrooms, feel free to ask an employee where the closest one is.
While there are more to be added, this has gone on longer than I intended so I should stop now. Hopefully, this will help the world be a SLIGHTLY happier place. I am not kidding about the change thing—hand it!
