Rude new manager/supervisor

I always took my two cars to get washed at Baywash and always received great service from the lady supervisor, for many years. But this and my loyalty changed in an instant when my wife and I was rudely greeted by a man who's only focus was on his laptop and dismissively told us that he wont do both cars only 1 as they close in 2 hours and shrugged his shoulders. I immediately turned around and went to Lemon tree. You have now lost a loyal client, it may not be much on your pocket, but be careful how you treat customers as they will leave one by one.
