Sally Beauty Supply

I have been to this Sally's before-no problems until today. I got to Sally's at 11:40am there was a sign on the door "be back in 15 mins" it is now 12:15 and still no one. I get they may have had to run to the bank, but they should have put up a sign saying be back at a certain time no be back in 15-that leaves it wide open, which made that's what they wanted. There was another lady that I spoke with she had been here longer than I had. This is been a real inconvenience.
