So, you ever get a numbnut customer in front of you, pointing to some patch of skin, or to their eye or something, and saying something like, "WHAT CAN I DO ABOUT THIS?" and you look at whatever they're pointing to, and it looks as normal as any other part of them?
This happens to me a lot, and I'm not sure if it's a problem with people's self-image, or a problem like I have a total lack of perception.
I'll usually just say something like "Does it itch?" to try and get a handle on what's going through their brain. People like it better when their pharmacist says something like "Does it itch?" as opposed to "You look just fine to me."
Not to mention about 60% of the time it does turn out to itch.
