I don't think your standards have been too high. I don't think you have been overly sensitive when it comes to this particular experience. I have just ranted twice about my past weekend and found myself mortified my displeasure came on a little too strong. But no, darn it. It was as bad as I have ranted. My voice carried others behind it. The difference is that I chose to speak up about it. So go ahead and do the same. Put in that complaint. Throw your weight around. Give yourself some satisfaction.
