I decided to leave without tipping after paying for my meal today.
That doesn't seem fair. Why didn't you tip for the meal you were served?
I don't feel like a need to tip for being served a meal.
You may have paid for your meal but its wrong to dash and dine without tipping. Tips provide income to waiters and waitresses. If you don't leave them a tip then they'll be upset that they weren't properly compensated.
It's not my fault that they aren't paid more, I shouldn't have to tip.
Tipping is how servers make most of their money. If you want to eat at a sit down restaurant it's customary for you to leave a tip. The servers work hard and deserve to be paid a fair wage.
