I ended up having to work from a cafe today for various reasons and it got me wondering about what cafe owners find acceptable.
I was there for 2hrs, spent £13 in total including a drink and then lunch. I sat at a table with another person on their laptop, and didn't use the electricity (although there were plugs provided). It's a large cafe and there was clearly enough space for lunchtime trade as far as I could see. I was near the entrance and those that wanted a table could have one as far as I can tell. I'd have moved otherwise.
I enjoyed it and would like to do it again. Is a drink and some lunch reasonable for 2 hours though?
