What is with the bad attitude of people who are being paid to help customers?

Like yesterday with the dental receptionist.

Today I tried to renew my (3) tags online, but got a message on the first one that said it was not renewable. I tried several different search options, got the same message.

I called the tag office to f ind out why. She was almost like, “Well what do you want me to do about it!” Not quite those words, but close. Then there was some dead air space while she waited for me to Do Something.
I finally said, “Could you look it up for me? Maybe it will give you more information than it’s giving me.”
Insert heavy, disgruntled sigh.
“OK. What is the renewal date.”
It was March 31.
“Well THAT’S why!” She said like, “You idiot!”
Since I’m late I have to physically go in to renew them.

Have you been experiencing weird, unprofessional levels of customer service lately?
