Example I mail a 000 buble mailer with one chip .60 oz. Two clerks charge .90 cents 2 clerks charge 1.95 The higher clerks won't even talk about the charge (very rude). So I now know the days the good guy & girl work, and go to them, even if I have to let a few people behind me go in front of me (I fake looking for my wallet) I never talk about the different charges to any of the clerks. Just weird, never had postage due,for the .90 er's, and mailed avgerage 3-4 a week. Also, the 2 good people are so friendly, know my name and we talk as friends, I see the other 2 being rude, and nasty, must hate thier job.
