Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
It depends on how they approach me, honestly. If they are demanding and condescending, talking smack about my garments, then I tell them we can not assist, there was a size chart listed in several places you were told to refer to. It also says at checkout to confirm your sizes, we are not responsible if you order the wrong size. -BUT- If they appear grateful, "I completely understand if you can't make one" and are nice about it, then we do it. DTF has come in handy for this. Comes with the territory I guess. We also charge more for store items so it's not really that lbig of a deal anymore. I try to put myself in the parents shoes and what would I do. I'd be a bit miffed if I ordered a hoodie and it doesn't fit so we try to be understanding.
