Not that I drive a ferrari, but I am scruffy and unshaven all the time.
There's once someone scruffy came in and asked for some cold and flu tablets for his wife a while ago and I immediately assume he's a runner. Anyway, after a bit of a drill and got his ID - quick glance at the license and I noticed a familiar last name. He's the husband of a very regular customer who buy all her gifts from our store (like weekly). I quickly trying to mend things on asking how's business etc etc. He doesn't drive a ferrari, but he does have a 7 series.
There's also a regular customer of mine always come in his shorts and singlets (unless he's just finished work) and sometimes scruffy (need to be political here
). He's a surgeon and drives a Murcielago.
You can't really tell from their looks.
