Dear teachers / Hi there (let me know which way of addressing you prefer)

I was at work and an arrogant customer ruined my day. I won't talk about it in details since this isn't the place to ramble on. I couldn't talk back much because I was angry and couldn't find words quick enough. After he left I thought I'd jot down what I would've told him if English came more natural to me.

I know there are some grammatical mistakes (Or sentences that doesn't sound right or could be better stated) and I want you to correct it for me.
Here goes nothing...


...Sir, if you have any complaints or anything to say do so in polite and rational manner, not insult a clerk that works here.

Obviously when you said 'you don't know that and you own a store?' you were personally insulting me. I find it very offending.

You didn't have to say that unless you wanted to intentionally make me feel bad.

Let ME tell you something.
This 'I'm better than you' attitude you have really irritates me. I detest people with haughty eyes, be that customers or total strangers. You're just that person and I'd rather not see you again. Please jack off and I'd very much appreciate it.


There may be other parts in the above paragraph with grammatical mistakes, but what particularly bothers me is the phrase 'be that', where I've boldened.

Basically what I want to say there is that I detest anyone with haughty eyes no matter who I'm dealing with. Could 'be that' be used there at all, and if it could, is my usage right?

Thanks in advance, and sorry for such... hateful paragraph. I just had to let it off my chest somehow.
