Precisely this. Empty shops have an unconscious (sometimes conscious) effect on people making them less likely to drop in themselves. 1-3 people taking up wifi and electricity could easily attract enough customers to pay for their visit with each stay. This does only really apply in shops in areas with decent foot traffic though.
