I would say its up to the customer to decide if he's overcharging. ....if he takes 4 days to do a quality job then charge for that....you never know you might charge the same and take 2 days.....dose that mean your overcharging. .? Imo its up to the client to do there homework and choose the best tiler for there project.....thats within there budget..
When you put it like that.......!
Seriously though, I see where you are coming from. I'm honest with my customers and admit that I am newer to the tiling trade and as such jobs will take me longer than a more experienced tiler would take. So far its not caused any problems and the more I tile the quicker I get so hopefuly that won't be a factor for me much longer.
