Both works. A is better for staff, —to not cross path with costumers that way often—, however it segregates the costumer's area layout. B has the costumer area nice and tidy, it will benefit whatever decoration and the overall experience of the place, however staff has less work-space, they would have to walk more; and also there could happen crowding at the entrance, —which I'm guessing is also the main exit—. I would choose B by asking the chance to detail more the bar area and the working process of the staff... If choosing A, then to ask for other chances of costumer layouts. 🤙  

 That all sounds right. Exactly where my heads at. 

Wifey and I are now leaning B. But only if we can fix the work area. 

Shop is run by one person. Me. Not expecting volume. It’s small on purpose.
