lines

i think waiting in line is very different in the US than in MX.  let me know what you think?
Today i had to go to the bank, why is another great story about mexico, but let's just stick with i had to go to the bank.
first you have to get a number, whenever you go to the bank you have to get a number.  i say it's because otherwise someone will push past you to "ask a quick question" that is actually a long process of questions and papers and... anyway.  and sometimes there is a person who helps you decide which button you press to get a number.  today.  she told me no number, just go behind this person, he is the last in line.  there are quite a few people in line already.  but the line is actally chairs and not a line.  imagine a block of 3 x 3 chairs.  this is the line.  in the first row are the first people in line, then the "line" snakes around to the second row and third row and finally the people who are standing because there are no more chairs.  but every time someone goes up to the teller window the "line" also has to move. so, everyone has to change seats.  seat 2 goes to seat 1, seat 3 goes to seat 2, etc etc.  it is really kind of awkward because seat 7 has to cross in front of the people seated in seats 8 and 9 to get to the seat 6...besides the fact that everyone has to change seats.  and besides the fact that one other person (an american) mentioned it was a little weird everyone acted as if this makes perfect sense.  does it?
