I stopped at Old Navy to buy some disposeable clothes. After 15 minutes I had an armload of stuff. When I got to the front there were 3 registers open, each with a line of about 25 people. I asked an employee who was standing at a closed register if they were gonna open any more lines, and he said "no, we're understaffed today." I plopped my stuff down on the counter, said "maybe next time then", and walked out.
