Bingo!They build the fee into the price of the food.
Here’s a reality check for you anti-cashless folks.
Why would a restaurant that hires folks who can’t get a job making above minimum wage want to deal with cash?
The restaurant risks loosing more money by employee theft or walk in thieves than cashless.
What are the thieves going to steel if there is no cash?
Cashless is purely to prevent theft, whether by employees or external. Maybe I am the oddball but I think it is a smart move. Plus most people under 50 don't even carry cash so the amount of business they lose is negligible.
