The 20% on everything is just ... I mean I got groceries delivered today, should I have tipped $20 for someone delivering $100 worth of groceries a couple blocks? Grocery delivery guy would be the best gig in town.
Dry cleaning? Should you tip $10 for someone delivering like 4 pieces of clothing?
It'd just be nuts if you tipped 20% on deliveries, we'd all go broke, really fast!
Four people order sandwiches at lunch, comes to $10 a piece, they're supposed to tip $8 or $10 (after tax) to the delivery guy? I guess grocery delivery would only be the second-hottest gig in town.
I cannot even IMAGINE what people would be tipping the kid from the liquor store!
