Things I don’t understand

There are little things that I just don’t understand. Maybe it’s just from my point of view that I don’t understand. Some things kinda make sense and yet, I still don’t understand. Take for example the simple function of vacuum cleaning. It seems this happens quite often to me, maybe to you too. I sit down in a restaurant, get my food and I’m all ready to take the first bite when an employee turns on the switch and begins vacuum cleaning practically right under my feet. Now you know that stuff is getting sucked into the bag, but did you know the exhaust is blowing all the dust up in the air and right onto the food? Or what about the restaurants that don’t use vacuum cleaners, but rather just sweep the carpet with a broom. You can just watch all the dust particles flying all over the place. Normally, the employee is sweeping it directly at a table full of guests. If the sunlight is coming thru a window you can really see the dust particles taking over the air. And all that dust is flying right onto the food. And what about the restaurants that don’t have carpet, just tile. There you are, sitting at the booth getting ready to take a bite and all of a sudden you hear the slop of a mop hitting the floor swooshing back and forth right near you. I don’t know, but it just seems so unclean to do that while people are eating just 10 inches away. I know they are doing it to keep the place clean. That’s the part I understand. But why do they have to do it while people are eating? Here’s another one. I’m talking to someone and every time I say something, the person says “what”. I repeat the statement and even before I am finished with the same sentence, the person answers. I say something else and here it comes again. “What”. So I begin the same thing over, and once again, I get interrupted with the their response. It’s obvious that the person has clearly heard and understood what I was saying the first time, every time, but invariably they make me say it again. Why? Maybe it’s not polite, but when I run across a person that wants everything repeated, I kind of ignore them when they say “what”. You know what happens? After a few seconds of quiet, they miraculously get their hearing back and respond to what I said just like they heard me the first time. And I don’t’ have to repeat anything after that. Ok, and here’s the last one for this issue. The push button game. On occasion I have called a business office to discuss some serious concerns when all I reached was endless pre-recorded messages asking me to push this number or that number. Probably a cost saving measure. The part I don’t understand is during the pre-recorded messages one is forced to listen to, they slipped in a phrase or two that says they were sorry for the delay and please stay on the line. Then all of a sudden, after several minutes of pushing button, you hear a click and the phone goes dead. So you have to start all over again. It seems to me that they apparently created the delays so that I would be frustrated enough to just hang up and forget it. I’d rather talk to a real live person most of the time.
