He may have 30yrs experience but it sure as hell isn't in tiling,sounds to me my friend like your a victom of an unscroupulous "hack attack"If I were you I'd get some green painters tape and put a small piece next to every bit of work he did that is not visually pleasing to your eye,the green tape sticks out and shows exactly how many mistakes he's made.Take a level and straight edge and mark where his lines are not level,grout lines that are out,toe stubbers etc..the more you mark,the more he'll see,and if there's a lot ,even an experienced setter has to be accountable.I would also have a proffessional setter come in and write you up a quote for how much he would charge for ripping it down,give him the quote and ask him what he's going to do about it,if you have green tape all over the place,dollars to doughnuts you won't hear from him again,if he offers to do the work,be wary,chances are he is a hack and isn't getting any real tile work.Definatly ask for references.I think he won't have many.And like buddy said earlier,name him,blame him,complain to the better buisness bureu and let your tile stores in town know.Usually a tiling,flooring store will give you names of reputable setters,good luck on that one Bud.
