I worked in a Mexican restaurant. We had a senior’s discount but policy states that we have to wait for them to ask for it. We weren’t supposed to just give it to them but sometimes I would just give it to obviously elder folks.
Once, after my standard greeting, I decide I will do so for a grey-haired man. But before he even places his order, he picks up my ‘take-a-penny, leave-a-penny cup’ with one hand, pours it into his palm, and puts all the change in his pocket. He even stares me in the eye the entire time as if to challenge me to do something about it.
To which I decide that he has taken his own senior discount. Too bad, because the one I would have given him would have saved him a lot more.
