I insist on defending it further. Just because you either can’t do a thing, or have not put in the time to try to learn how to do a thing because you simply assumed it was impossible does not mean that I can’t do it. Human beings are rather simple things, and extremely predictable and their faces read like a book, if you know how to look for it. Its kind of weird, actually. Studies have indicated that children can actually read people better than adults can; I kind of think that instead of failing to learn it, society tries to make us unlearn it with such asinine things as “you can’t judge a book by its cover”.
Maybe you can’t judge a libary book by the color of its cover, but you can sure judge it through other things. A book with well ruffled pages has been read much. One that has a worn cover has been treated with a lack of respect. A book with a stiff and pristine spine has never been opened; this actually reads as an no-read, because we don’t know how anyone reacted to a book they never opened. But if only the beginning of the book is heavily ruffled, we can then ascertain that it probably isn’t a very good book. If the title reads like click bait, it probably has no substance, since there was no other reason to pick it up. And so on and so forth. People are very much the same.
If you look at me, you can tell a lot. I have a broken nose, and a cauliflower ear- I have been in a lot of fights in my life. I am very overweight and have discolorations from scars on my skin- I am diabetic and not in good health. I limp and walk with a cane- same thing. My hands shake and I have flushed skin- because I am an alcoholic. The fact that I look unkempt and have a beard down to my chest is suggestive that I am not interested in presenting a good physical appearence. You couldn’t read any of this? I bet you could if you tried to learn.
As you said, and you are right, if the employee was having a bad day, she would not have been helpful to me, especially in a manner that precluded me spending more money on a more expensive material that would have also done the job, but made her employer more money. She also thoroughly criticized her employer to the customer infront of me in line. As did several of her co-workers. A culture of criticism of an employer is usually a bad sign.
I’m sure I have had employees who don’t like me; I know I have. Actually, its simply a balance of probability- almost nobody likes me. I don’t blame them; I am insufferable. But when they start telling customers such a thing, it is time for them to go.
