Nowhere near the OP (UK) but I've noticed a lot of fun-only lanes arent bothering to rent shoes and just let you wear whatever you have.

We just charge a flat rate with shoes included. We do $5 / person or $25 for a whole hour for larger groups. Wanted to take some of the advanced calculus out of the price of bowling, yknow?

Isn't that included in the lane price? Always has been for me.
