I don't worry about the competition, and I don't go searching them out on FB or any other social media outlet.
Since I started my own business many years ago I always made it a point to get on with the 'competition' way back in my first business there was a salon around the corner who used the same product range as me, if I was fully booked when someone new called me I would recommend the other salon. Eventually they did the same for me. When I gave up my business to move into Education my employee was immediately snapped up by them and still works for them today
Recently I had to take several months off from my current business, and I knew a salon nearby used the same gel polish as me and I recommended it to my clients.
Now I am back at work, all of my clients have come back to me including the few that went to the other salon.
I don't know the staff at the other salon, but I am extremely grateful that they looked after these clients, therefore I handed in some flowers and chocolates for them all with a card expressing my thanks.
I know it may be different for me working in a small town rather than a city or somewhere that has lots of discount nail bars, and I am as busy as I want to be, but I just don't believe in making an enemy out of people who are just trying to make a living the same as me.
