Do any lasertag places (particularly those more focused on milsim, eg iCombat) ever charge for "ammo"?

Ok, so I had a stupid idea, and it stems from my days as a paintballer. A lot of field I frequented as a newb charged a rental with a certain amount of painballs (ie: ammo). Has anyone ever heard of someone doing this for laser tag? Obviously there is no real ammo, but with iCombat there are magazine reloads and co2 is a consumable. Would having a set amount of ammo (obviously a reasonable amount) and the ability to buy additional ammo be a deal breaker? I'm thinking this could reduce the cost of entry, but keep the average spend per guest at the same rate of the standard unlimited model.
