The point is there are two possible responses to seeing the surcharge: "just raise your prices" and "I can't believe I have to pay more for this shit service! At least we know its not
the owner's fault the prices have gone up, its probably those liberals forcing us to pay other people's hospital bills!" (I've also seen "employee sick-leave surcharge" appended after Oregon mandated that restaurant employees receive paid sick leave, and I've heard diners grumbling about it).
I've been cussed at for charging 5 cents for a bag when the city I worked in mandated such fees ("Well, I'm from the next town over, where bags are still free, you shouldn't charge me for that" "You're shopping here now" "That fee is bullshit, get your manager NOW" "OK")
The point is that if you work in the service sector, you rapidly realize that customers have a choice about whether or not to patronize businesses with transparently shitty policies. That those businesses stay in business tells you something about the ethics of the people who give them their business. And how those customers treat the employees tells you the rest. The point, as I've made a couple of times now, is that the customers of shitty businesses share some of the blame for their shitty, abusive business practices.
