I have zero data on this, but I'll lay decent money that 90% of take-out coffee customers go to the same shop regularly.
After all, they're going somewhere, probably somewhere local, with their coffee. If they weren't, they'd stay at the coffee shop to drink their coffee. Or if they're not going somewhere local, then they're on a long journey (not that common).
I used to drink most take-out coffee when I worked just around the corner from the coffee stand, and went there every day, twice a day, for decent coffee.
