I'd add tipping system for various services, but specially restaurants etc in definition of corruption too. Here blame pass around between employees, owners, restaurant associations, govt officials making/ passing laws etc. But end result is customer keep paying extra charges or being labeled as worst customers.

I love how media is in this game , printing endless articles how customers are really supposed to pay tips because poor server. And even when customers are revolting against tipping culture it is going from 25% to 22% as a way of speaking truth to power.
