Someone called the cab at FMH emergancy room this morning around 0425. The Cab arrived at about 0430 when I saw it outside briefly. The cab couldn't have been there for more than a minute when suddenly it pulled up further and flashed a large flashlight through the window to grab the attention of the gentleman who was talking with security. I thought this was very unprofessional, not good customer service, and above all rude. This cab driver seemed very in a hurry and should not be in a customer service position if they dont know how to display good customer service. I understand they do not want to be waiting, but I saw the cab out there and it really was not there for more than a minute.
