content: For a single incident, I would just swallow it.  After these few incidents, I will not use any cab in Charlotte especially from the airport.\nA month ago, I called a cab to the airport early in the morning.  I made it very clear that I need the cab at my house at 6 am as I have a flt to fly out.  I asked if that was posssible, the operator said yes.  It was around midnight when I called.\nAt 6 am, I looked over the window, there was no cab.  6:05 no cab.  I got nervous as I was catching a flt to go to work.  I called yellow cab again, then she said there was no cab available.  I screamed as I would miss my flight to work.  She said she was trying but she had never notified me earlier.  I couldn't wait as the clock ticks. I had no other choice but to wake up my neighbor to give me a ride.  Thank God, with the kindness of my neighbor and my professionalism, I ran and ran and ran inside the airport and finally got to the gate be the last one before they closed the door.\n3 weeks ago, I came home at the airport to take a cab since my house was within 3-4 miles.  It was my first time using a cab.  I didn't know how much here but I had in San Francisco for less than $15 (with airline discount, they charge $12).  So I thought I better to use a cab instead of calling friends around.  I need to go to my house to get my car key then to the hotel right by the airport to get my car.  I explained very clearly to the cab driver who said nothing about the charge.  He didn't turn on the meter as I thought charge shown on meter.  As I got to my house, he said he would charge me double.  I asked how much and why double and what was supposed to be?  He started to yell at me.  Finally, I was charged $28 for a 6 miles ride.  I didn't know if that was acceptable.  I said  to myself I learned, if he overcharged me, I treated that as donation and God blesses.  I was too busy.\nLast night, I took a cab again from CLT airport just to go home that was really 4 miles.  The driver was acting like a wild animal, very unfriendly, talking everything I had no idea what he was talking.  He kept saying I had no idea how long people were waiting.  I asked what people?  Other passengers?  They were behind me and shouldn't be longer than me.  Or the drivers?  I even asked him to take me back to the airport if he didn't want to have the business.  He was driving crazy and I hoped there was a police car closed by.  Unfortunately when we want to see a cop, they were not there but when we didn't want to see them, there was always one.\nFinally, I was safe home.  I still could not understand what was going wrong with these cab drivers.  If someone can help to explain to me.\nBTW, if these cab drivers hate their work, find another one.  I was still figuring out what was their problem.  Perhaps, a few miles were too short the trip?  They were looking for someone who needs to go 100 miles or to another city?  For long ride, people will rent a car for $20-$30 a day and gas.  People need a cab if that is more economic than renting a car for a day.  Anyway, at least I understand why they are still driving an angry cab cos they don't know how to do maths.
