Remember, looks are not everything. I also owned a large car dealership and found out that very often, the one person coming in looking like a slob with not a penny in their pockets would pay cash for a $40,000 automobile. My sales people learned fast to treat everyone with the same respect.
Unfortunately, in our society, we are too pre occupied with looks and impressions. Again, dress appropriately for the job. But don't be fooled by the dress the person is wearing. Look at the credentials, look at the product and then judge their work, not their appearance.
BTW, what is wrong with a Hippie. They are good people too. Sometimes I look like a red neck and I even carry. So here is gun carrying hippie who also is a darn good appraiser.
Cheers, back to a beer.
I guess we don't want to go into who has tattoos and where and what they are? GRIN. That really could be unprofessional.
