Stupid things you are supposed to tip for

[TheCentaur]

Taxi rides. You either do your job and get me there alive or not. What's the tip for?

[greenhippo]

Donut shop, Starbucks.

Although I rarely go the former and never the latter.

These places should just include "tips" into the cost and eliminate all the BS

[HoulihansTX]

Subway(restaurant) Tip jar.

[thebestthereis]

Strip club
