#34 Pays in More Ways Than One

I learned this one after receiving a “tip” from a server at a popular national chain. The server told me, “Our location has some discount options that we can apply at the push of the screen. Typically, we only use them when the customer presents ID or requests it, but once in a while we can use them to our advantage.” He was right. They could use those codes for extreme revenge.
“If I get particularly rude customers, especially if it’s a group of 40-something ladies who dress and act like they’re a wannabe cast of some version of Housewives, but are actually so cheap that they are coming to a place like this, I totally hit that seniors discount button before presenting their check. While they comb over the check because they just know I must have made errors, they see that I must have assumed they are in their 60s. I don’t care about reducing the price of their check. It’s not like they were going to tip me much anyway.”
