I own my own business and am the only employee.

There are 2 people who come into my shop from time to time, that just irritate me.

The first is just a loud-mouth jerk..I'll call him "x". and he likes to "yank my chain" so to speak. I am an expert in a field with very few practitioners... and yet, he likes to ask my advice about this field, then ignore my remarks. He also wastes my time by bragging about whatever he's been up to lately. Every once in a while, he will loudly criticize some action of mine. I know several other people that know him, and not one has anything good to say about the guy.

I want to be rid of him. I don't want to cause a scene... I just want him to stop coming into my shop.

The other person who irritates me is an older fellow who apparently has a lot of friends in this small town where I live and operate my shop. I'll call him "y". Every once in a while someone will come and pronounce "y sent me.". Then proceed to criticize me and/or my shop. Y himself also comes in every once in a while. He doesn't talk loudly or say anything overtly rude... but, I'm left every time with the feeling that I've been insulted by his subtle, underhanded, insulting behavior.
I suspect he sees himself as a competitor, and is playing mind games with me. I almost feel like taking notes to see if I can make a harassment case out of it. I actually know the president of the local chamber of commerce, and mentioned what was going on. But, I'm not sure if she gets it, or even believes me.

Anyway, when they're here, I start to feel stress, and feel like getting away from them. Unfortunately, as I'm the only one in the shop, there is no place to go.

As luck would have it, they were both in my shop today, at the same time. Y said he saw X in my shop, and stopped in to say hello. Then they stood there and chatted for a while. At least they didn't stay for very long.

I may check in from time to time with updates.
