I honestly believe you are thinking to much into it, if you have staff that smell, if that be of smoke , b/o,bad breath or to much perfume, then just tell them. What staff do on THEIR break as NOTHING to do with you. Smoking is part of society nothing you can do about it, ALL therapists should be washing their hands before and after every client, regardless if they smoke or not. You may feel a therapist that smokes does not give the right image, but what about the therapist that is larger than a size 8/10 , would you employ them ? What if one of your staff starting gaining weight, would you bring that up ? nobody wonts a massage or brow wax from someone who s hands stink of smoke, but neither would they wont a body wrap or diet advice from a size 12 therapist. Would you wont a Brazilian from an over weight size 14 waxing expert , how on earth could someone that size be expected to advise your client on what looks good ? Would you wont a size 16 therapist doing your make up, what kind of image is that giving ? TBH i find your post very very offensive , just like my observations above !!!!!!!!!!!!!!!! do not worry about if your staff smoke or not , just worry about how well they work. p.s. I DO NOT SMOKE & NEVER HAVE.
