LOL you go for it ... free advertising for life if you get a shop up and running ... oh and stay as mod on here :)
I do vaguely remember the Body shop doing this .. but what my 'minds eye' sees is a shop filled will 'pub like' pumps (not sure where the cellar is for the barrels lol !!) Ooo unless you'd need a pub to do it !!
Wall optics and maybe 'cocktail' type recipes to choose from ... !!
Communications from all the poo and cream manufacturers - discounts for returned & refilled bottles/refunds for just returned bottles (in case you fancied a change !!) pump dispensers like the wall mounted school ones so you could buy pouches to put in !

the list goes on ...sighhh !!
