'cus, a while back there was this Thing about it being a toxic carcinogen (and what isn't, these days, amiright) and... well I happen to be in the customer service side of things and I handle a lot of receipts. Like, a lot alot. Too many. Do I... should I... wig the fuck out? Or is this one of those overstated things, like the big cups that did or did not have lead in them?
When I worked at grocery stores, I always wore gloves because I didn't want to touch receipts (among other things, like raw chicken slime and blood, etc.) all day. Plus I had better grip.My gloves would be black after a while.
You probably don't need to worry about holding it after buying something, but if you have prolonged contact with it (such as cashiers, post office workers, printing shops, etc.) then yes yyou should be concerned.
