I work at a nice little bakery. For the most part, the people are nice and everything goes smoothly! One time, this lady had bought a few things and her total had sort of a weird number because of one item (It normally comes out to multiples of 5 because we don't charge tax on most items). That was fine, no biggie. She hands me a five and some coins and I start to count out her change. Right when I finish she pulls out another handful of coins from her pocket and dumps it on the counter. I start trying to recount everything and when it takes more than two seconds she blows. She gives a condescending laugh and starts going on and on about how "Back in my day we didn't have to rely on computers and calculators. We knew how to count. I just think it's funny how cashiers don't even have to learn basic math anymore" etc. Like, chill. I already had your change, you just decided to make me recount. Please stop talking.
Another lady came in like 10 minutes to close and asked for coffee. We were completely out and normally we don't have many people ask for coffee (maybe like 2 or 3 a day) so I told her this. She puts her hands on her hips and goes "Oh, I can wait. Go brew some more." And I'm just like??? You want me to make up another pot just for you?? No one else is gonna buy any, we close soon and you'll probably be our last customer. The thing is, the bakery is right next to a COFFEE SHOP which is open well into the night and has much better coffee than us?? Even if the coffee shop was closed, we're also across the street from a gas station that will have coffee, and more options for said coffee than us. To top it off, I was sorta stressing and rushing to get her coffee and clean up for the night. I ring it up and ask if she wanted anything else to which she replied "Oh no thanks. I can see I'm stressing you out. I don't want to give you more than you can handle :) ." I wanted to strangle her by the time she left.
