BOO! I get it- it's Saturday and you're busy. But I called and you told me 10 minutes so you take my name and I rush over. I get there in 4 minutes. I proceed to sit for 15. Then you put me in a chair where I wait for another 15 minutes. I had to leave. I was squeezing in a manicure as it was. I get that you're busy but don't tell customers 10 minutes when the reality is 40+. Now I've wasted 40 minutes, still have no manicure and I'm grumpy.
