We always tip at least 20% but that seems too little considering most of these servers are single and probably also raising a kid. And note the cars parked in the employee parking lot, barely running on four wheels. So for me 40 - 50% is always the tip I tip. And now a day with so much food to go orders instead of sit down dinning, those servers are really hurting so I always give a good tip for orders to go. After all, they did package the food and included the condiments, so that is worth something. Plus, with all the restaurants and fast food so short staffed unable to find workers, just be thankful someone is still willing to work. And tip them accordingly. Twice now it broke my heart when I tipped generously and the waitress broke down in tears "Thank you, I needed this so much". What do you say to that?
Just imagine if all the restaurants and fast food were closed due to lack of staffing? And you have to actually cook.... yourself.... at home....? The mess, the time involved, the clean-up, the crappy tasting food because I hate my cooking. Well then, isn't it worth a generous tip to keep the establishment open so you don't have to cook yourself? Priceless!
