don't ever fuck with the people who prepare your food

It’s difficult to find a place that doesn’t do that these days.

The guys likely to spit in the food are the same people who don't care the slightest bit about the business and are probably going to end up fired after a couple of months for not showing up getting in a fight with a coworker or manager. And this isn't me trying to bad mouth service industry folks, it's just that people who are working in fast food are usually are not in that situation because they're making life decisions that lead to financial success (again generally not specifically). The point being the person spitting in your food isn't going to care if you come back.

This is what I've done. There are a few restaurants that I've come across that have mandatory tipping, and I'll never go back. I don't think it's insensitive to believe that it is not the customers responsibility to pay for the employees.

Raise the prices, get rid of tipping, it will make everyone happier.

This is the way. I recently got an oil change, and at the end I was prompted to tip with the default 20%. I changed it to zero - the person doing the work is certainly being paid market rates and well above minimum wage (even now, why do I feel the need to explain myself?!) and I’ll never go back to this chain.
