I've had delivery drivers say to me "there's only 4 dollars here" on a order of like 30 bucks. It's happened several times. The last guy that did that I told him to give me the tip back and we started arguing at my door. I said "your not fucking waiter buddy! There's no 15% general rule here. Delivery guys get what they get". After our little verbal battle I let him keep the tip as he walked away with a knot his face. I called Swisschalet and blasted them. I said "I don't ever want to hear your delivery drives bitch again about me giving them a tip again. Send a memo to your stores... do whatever you gotta do, but this is the second time this has happened. I told her it ruined my appetite due the fact I was all riled up after fighting with the guy at my door. I explained to her I used to be a restaurant manager and any of my waiters every pulled a stunt like that they would suspended if not fired and they had way more a right to as they waiters!!
Then I had a similar situation with a guy at Mama's Pizza. Delivery time was supposed to be 45 minutes. An hour and 15 minutes go by and I call to cancel cause I'm like this is crazy. They tell me the guy left 10 minutes ago and should be there any minute so I agree not to cancel my order. Finally guys shows up and is like "there's only 4.50 here....
I let him have it fucking double barrels. The balls on this guy....shows up with a pizza almost an hour and half after I order and complains about almost a 5 buck tip....
After I gave it to the driver called the owner let him have it as well.
