And if your printer is snippy with you, just get snippy right back! You're the customer and the one who pays his/her wages, so you don't need to take shit from anyone at the printers. Bu you don't need to give any either. Simply tell Snippy that you need some advice and that if Snippy can't provide it in a civil tone, you'll ask the same questions of Snippy's superior with an explanation of why you're "bothering" him/her.
