We always tip at least 15%, but usually 20%. Think of it this way:
1. They usually have to use their own car. But if the company provides it, they get less hourly wage.
2. They have to pay for gas.
3. If the weather is crappy, they still deliver.
4. You (me) didn't want to go out, so they are doing what you didn't feel like making or driving out to get.
Just a thought. You paid a little less that 15%, which isn't bad. Hope your food was hot and tasty.
