Tap to pay probably doesn't help with getting people into the alley but probably helps with 'one more game'.

Your beginners have to come for shoes anyway, and the pointer to which lanes to take (you don't want them taking a lane at 6:30 that's reserved at 7)

At least you could display a message that says "this lane is reserved. Open lanes: 6, 7"

I'm sorry which lanes are open again?

Did you really just claim a username to reply? Love it, someone’s more bored than me. 9-10.

Available lanes are lit green and reserved are red ?

(Or something more complex)
