Where's MY grace?

I'm at Lewis the other day, standing in line at the customer service desk to mail a package for work. There's at least 6 people in front of me, all mailing packages. No worries. At least 3 of them require additional assistance with their packages. One woman put a priority label on her package and wasn't supposed to (the Lewis worker helped her find the correct label). Another woman hadn't even addressed her envelope or put the contents into it (a second Lewis worker let her do it right there instead of doing it over at the table where she should have done it to avoid getting out of line). Another woman was unsure how to ship her package and what priority box she needed (the first Lewis worker found her the right one).

I was pleasantlty surprised at the great service these other patrons were receiving . . . until it was my turn! I was mailing some pictures in a manilla envelope- the kind with the metal clasp- and was told (several times) that I wasn't allowed to mail it with the clasps. The Lewis worker almost begrudgingly put a piece of tape over it all the while explaining that this is bad for the machine that sorts the mail. So bad, in fact, that it's almost the worst kind of mail to send (really? Is there a 'most wanted' poster that depicts the worst type of mail to send?!?). The second worker piped in about wondering why they even make this envelope anymore because it is such a hassle. Nevermind you the previous patrons in front of me who were uneducated and unprepared, I get the lecture because of a metal clasp! Tis the season . . .
