Sandles's okay then

I expected many more people to ridicule me for wearing sandles to work. I skipped the suit coat, and I've got on normal pleated trousers, not suit pants. I'm still wearing a tie though, that's the only incogruence I see. The receptionist at work though told me I'm crazy, that sandles are not propper work attire..."what will students think, you have to set an example!" Here's my example: wear sandles, it's hot out! Since only one person ridiculed me, I guess it's okay.
