Agreed. I would get take-out 100% of the time if certain foods traveled better. I have little interest in the actual 'service' experience, if I could manage my own drinks and pick up my meals directly from the kitchen I'd be quite happy. I don't eat out to be waited on, I eat out for the food. I've become quite fond of buffets in recent years.
Easily 9 out of 10 times I tip it's only because it's expected. I don't remember the last time I had good (or bad) service. It's all basically the same everywhere I go. I would feel better about tipping if it was earned rather than pressured to supplement waitstaff income.
