Well I can't really see that working, but lets say it does up to a point, until the queue starts building, but unless they sort something out along the same lines in shopping centres, especially when people have kids with them plus the older generation, who won't go out unless they know there's a toilet at hand, then shops are not going to make it. Plus all the shops I've been in have closed there changing rooms, some people will not buy unless they can try, who wants to keep going back and forth taking stuff back?
