Howling at the Lunacy

This has to be one of my least favorite days of the year...the day when many businesses give their employees an opportunity to prove just what idiots they are. Here's what I mean. On October 31st of last year, I go into a bank to tend to some important business. The vice-president, or whatever the title of the person with whom I'm speaking, is dressed like a werewolf. I guess if you spend every day of the year dealing with massive growths of ear hair, Halloween is a godsend.
But get real. How can I discuss my personal business with some moron who thinks it's acceptable to come to work like that? Same thing at the dentist office. The assistant wants to probe my mouth, but she looks like a witch. I mean like a real witch. She has the pointed hat and the fake mole (or maybe it's a real mole, I didn't test it), and the black dress. I really don't want something like that putting her hand in my mouth.
I refuse to go into restaurants or stores which allow their employees to dress up for Halloween. My thinking is that anyone who thinks it's okay to do business while wearing some ludicrous costume, is not someone with whom I want to do business.
I used to work for a major customer service center, and I hated going in to work on Halloween. While most of the employees chose some sort of ghoulish costume, there were a significant number of the guys who looked like they were straight from Transvestylvania, if you know what I mean.
I don't think it's prudish to expect men to dress like men, even if you do allow them to put on some ridiculous costume. Call me sissyphobic if you will, but I really don't feel comfortable in that environment.
Something else I don't get is why people wish one another "Happy Halloween." What exactly does that mean? I'm talking grown adults speaking with other grown adults. Is there some gayety (no pun intended) about the day that I'm not getting? How does one have a happy Halloween? It's not a day off from work. It's not a day to gather with the family and reflect on life's blessings. It is a day when almost every year I come close to mowing down some kid with a mask over his eyes, wandering back and forth across the roadways in the dark. I don't find it particularly happifying. There is only one thing I like about Halloween...the day after. Not just because I won't have to deal with the stupidity for another year, but also because that's the day the candy goes on sale.
