Clients,without them we wouldn't have a business.Employees would come a close 2nd but I don't have any yet.
I think giving the best service you can to your client from the minute they walk through the door to the minute they leave.
Listening to their needs and anxiety's.I like to pamper my client,Making sure they are comfortable,give them extra cusions or rolled up towels to make them as comfortable as possible throughout their treatment.A heated wheatgerm bag popped under their feet if they are cold,an assortment of refreshments other than bog standard tea or coffee,and not the cheap smart price brands.There is nothing more off putting than a cup of tea made with a cheap tea bag.
Using quality products and being up to date on latest trends,treatments and products.
No,no's for me would be talking about people in a nasty way to your client,talking about your problems to them(they are a paying client,not your friend,and they do not want to hear about your issues...well most don't generally)
Going that extra mile is important,you want them to go away and tell their friends and family that they had a good treatment and that you were professional and hospitable,word of mouth is the best advertisment around,spreads quicker than wild fire.
