What do you mean charge 20%? How sure is the consumer to be that that 20% goes to the employees?
Are they just tacking on 20% because they realize they can get that extra fee for no reason? It’s bullshit and predatory. People are looking at prices to judge where they want to/can afford to eat at and this behavior makes the business look cheaper at first glance.
No, fuck that shit. No tipping and no “service fee” bullshit. Just give us normal, straight prices on the menu. If you cannot afford to pay your staff at the prices for the meals, raise the prices.
I’ve seen places that even write on the menu “to pay our employees a living wage” or similar to justify the fee. Which again, is fucking bullshit! A businesses inability to price its product is no reason for me to deal with fees.
