The problem with this suggestion is that the floor that Starbucks occupies costs a fortune. The author says it himself: he'd be willing to pay "a small" fee to hang out in a Starbucks for 3 to 5 hours. If you were to actually look what this space costs Starbucks to rent, I'm sure it would amaze you.
Starbucks isn't your office. Hanging around and having a chat is one thing, but staying for upwards of 5 hours is just excessive.
Well i'd say it averages around 3 hours. There was one session that went up to nearly 5. It never actually went past 5.
If there were multiple parties that were attending, and regularly at that, surely their menu spend would make-up for it?
Without my regular coaching sessions, i would visit starbucks, at best once every 5 or 6 weeks. This way, they see me every week, and i spend with them every week too. As a group of us, its guaranteed spend each week.
