Dude, No.

Today a new guy started. He's a college student who's just here to help out during the summer. He showed up for his first day at a brand new job wearing a slightly ratty long-sleeved t-shirt (with sunglasses tucked in the collar), a baggy pair of shorts, and flip-flops.

To be fair, he said he asked the boss about flip-flops and was told they were ok. We think she didn't know what flip-flops were. (She's a little clueless sometimes, and probably thought they were real sandals.)
