The elderly often offered sincere tips of a dime or 25 cents, as if to say "Now you can use that shiny quarter to buy a new suit, take the streetcar downtown, catch a show with your girlfriend, have something nice to eat at the drugstore counter afterwards, and ride the trolley back home, with something left over to buy a few packs of Chesterfields the next day.."
Deliveries to hospitals suck. The staff takes forever to meet me to get the pizza, and the tips are always terrible. One driver, after getting stiffed at the VA hospital psych ward, claimed to yell "TET! TET!" before he left. Pandemonium apparently broke out."
We were too busy to 420. Usually, that's at the smaller pizzerias, where deliveries are less frequent.
Planning student trick: During slow times, send anew driver on a delivery to an address on a ghost street. When they can't find the house, much less the street, insist that they're a regular customer, and send 'em back. Good times.
In Geneseo, I worked in the dining hall, and took special orders from diners who wanted veggie burgers, etc. instead of asking their name, i'd make one up for them, if the diner was amenable, until the crabby lunch lady who had to go into the dining room to yell "Sunshine Happypants" or "Moonbeam MacGuillicudy" complained to Pete the manager who put the kibosh on my shenanigans. sigh.
