Walmart reviews

I thought the customer came first, will today I witness a customer needing help, the employee called for another employee to help, she new he could help. But Trish, I think it was her name, asked what he was doing ,employee stated he was helping a customer. Trish lashed out at said employee and told him where to go. Said employee tried to explain what the customer wanted she turns away and leaves, the employee and customer. She didn't help I was told she was in a bad mood when she came in, that's no excuse.
