I've recently started to learn line dancing.  This has been an activity I've wanted to do for some time and so I look forward to attending each class.  Today I left my home in what I thought was plenty of time to make the class.  When I arrived at the community center, I discovered a line of 8 or so fiftyish + ladies which was unusual but I thought, gee we're going to have a big class today.  I settled into the back of the line thinking time was still on my side.  Well, the line didn't move so I started to pay attention to the loud voices at the front of the line.  There were two ladies vehemently insisting that their brand of credit card be accepted when the attendant at the desk advised they did not take that credit card provider.  This argument went on for over 20 minutes.  By this time, I could hear the music playing in the dance area and the desk attendant gave up and took their names for follow up by a supervisor and let them go to the class.  So, I still had 8 or so ahead of me.  I discovered each lady was putting only $4 on her credit card.  This meant the clerk had to type in all the information into the computer which was a slow, arduous process while the music kept playing in the dance area and the hands on the clock kept moving forward.  When I finally reached the desk, I advised I had paid my fees in advance and she said I could just go to the class and wished she'd known that earlier.  Well, the first dance was rather complex so I didn't catch on very well since they were pretty much to the end of that session when I could finally start dancing.  I found myself feeling  quite put out by the two ladies who caused all the fuss....they got the benefit of the full class, and totally ignored the inconvenience they caused the rest of us.  I also wondered about the "why" each of the 8 ladies ahead of me only chose to put $4 on a credit card when they could have applied an amount for several dances since the fees are fully refundable and it speeds up the check in process.  My overall feeling of consternation toward all these ladies still brings a bead of sweat to my fiftyish brow.  I surely hope that regardless of what age I might reach, I will never be so totally oblivious to the common courtesy others are due in a public environment.
