I don't understand tip calculators, and I suck at math. I'd feel like a cheapskate sitting there punching numbers into my phone. I divide by ten then double.
20% tip in your country? Ouch. I’m guessing US: is it true that waiters/waitresses can be paid below the minimum wage on the assumption that tips can bring it up?
Officially, you're supposed to tip 15%. 20% is just easier to calculate.
Waitstaff in any restaurant you've heard of are probably not being paid below the minimum wage. I'm pretty sure the waitress we tipped at L2o was making solid money without my gratuity. It's just a social convention.
I'm still under the impression that standard tip in the US is 15%, but I usually tip 20% if the service is good, if only because it makes calculations is easier. Shoddy service that's not bad enough to notice is 15%; anything less jumps a quantum level down to zero.
