Considering the size and makeup of the Roman empire, I wouldn't be surprised if there were substantial differences in every-day purely utilitarian activities for no other reason than "that's how we do it here". People didn't even speak the same language (Britain never adopted Latin as a common language, and Gaul didn't until after these devices are dated). Unfortunately a lot of these details about every-day life are lost to history as no one bothered to write it down "as everyone already knows about it".
