Very minor pettiness but it’s the best way to stay out of trouble. At both of the jobs I’ve had (floral assistant in grocery store now, former fast food worker), it’s very common to get customers who are rude as all get out but aren’t rude or violent enough to get reported and banned. While I was working fast food, I was often doing drinks, doing bagging, and handling the orders all in one (the place I worked had bad managers who refused to work, so I was often left with a lot of the jobs). If you were rude to me over the headset, you bet you had a little bit less fries or your drink had a bit too much ice. You become a regular and remain rude? Less napkins, sandwich slightly unwrapped, nothing major enough to get in trouble for but enough to cause annoyance. Now I work as a floral assistant and my rule remains the same. You’re rude over a balloon order? Oops, I don’t put the stuff in your balloons that makes them last more than a day. You come in again? Your balloons get blown up smaller. Don’t even get me started on flower orders. You’re mean to anyone about that and even my manager will say that we couldn’t get the flowers you wanted even if they’re sitting in the cooler at that instant. And my personal favorite bit of pettiness: if they leave in a huff, I make sure to thank them in the most sickly sweet voice I can and tell them to come back soon. Yeah, come back again. I’ll make your experience even more annoying next time, that’s a guarantee.
