Shortly after my initial arrival to Czechoslovakia, I caught some European strain of flu, so I went to the run-down looking medical center in town and I noticed this strange box of cloth bags in the entryway into the building. Out of curiosity I stood there and tried to figure out for what they could possibly be used. After much thought, I concluded that maybe they were for people to put on their heads, kind of like the sanitary hair nets for American restaurant kitchen employees. I put one of these cloth bags on my head and it fit perfect, so I figured I had been smart enough to follow the Czech rules without needing to be told. I walked on into the building when some cleaning lady holding a mop started yelling strange irate things to me in Czech. I had no idea why she was upset. She was pointing at my hygienic hair net, then she pointed behind me, so I turned and saw some lady who had come in after me taking a couple of those bags out of the box. She then placed these bags over her shoes like cloth galoshes. I quickly removed the bag from my head and laughed, but the cleaning lady didn´t see any humor in it, she started yelling at me some more. I had never in my life seen a lady with cloth bags over her feet. I would have felt very embarrassed to put such ridiculous looking bags on my feet. I ignored the cleaning lady because, even if I was supposed to use these weird cloth footbags, it was nevertheless incredibly rude for her to yell at a client or customer (a very American point of view). The client is not the one to be inconvenienced or insulted ever, if at all possible, and here was some lady yelling at me like I should feel beneath her omnipotent custodial powers. In America, a janitor would never act that way, they are there to sweep and mop up after the customers or clients. They might ask you nicely to please not step on some wet place they have just mopped up, but yelling is something they would never do.
