I agree with your response, it's pretty much the one I wanted to write!

I would add that I work very often from coffee shops (and restaurants). In my mind being a good camper is: - Get to know your server/waitron's name's and interests - Become a good "regular". To me that includes not being rude or impatient. Let the non-regulars go first. If things are getting too busy I'll move to a smaller table or even leave. Yes you're a customer, but you're also supporting the staff. - Buy a meal if you're there for long enough that you would need to eat. If I'm spending the day I'll get breakfast at home, coffees at the coffee shop, order lunch, more drinks and head home before the dinner rush. - Tip well. This covers a multitude of sins.

Ultimately, let respect for others guide your choices.
