Here's a tip.
Don't tell me to put the receipt in the bag before I even print it. Or if you do, don't take the bag before I have the chance to put the receipt in it.
Like, you went to the trouble of telling me specifically that you wanted the receipt in the bag, but then you took the bag away from me? How is that rational?
It makes me so angry.
And it especially makes me angry because it's rude to tell me this beforehand at all. Like, you're interrupting whatever I'm doing to tell me to put the receipt in the bag when I would ask you about it at some point anyway.
And this isn't even a "this happened one time" story. It's happened many, many times.
