Look for a clock

"Was it an hour already?" Was all the Lauren could think of. She had no way to check her own phone, so she had to find another clock to confirm before heading to the changing room and taking off this horrible thing!

She traversed the labyrinth frantically looking for any clock that seemed to work, but the only one she found so far was showing 9:30 and she was sure she did not spend over four hours in this store.

Then she heard it. The gong. The same gong she heard right after she got a phone call from her employer. Before she put on a costume!
