And what else would be on that list of 'potentially offending clients'?
Applicants biting their fingernails, having dreadlocks, wearing a pendant with a cross, wearing a head scarf, dark skin colour, white skin colour, a foreign accent?
I find your way of thinking rather appauling.
But, maybe that is because I live in a country where about a third of the population has got tatoos ... and nobody understands why this should offend anyone; it's rather an interesting way of starting a conversation...
