Life as I know it

I like to go and get a manicure and or a pedicure sometimes, I go to different shops because I get these spur of the moments cravings for it. The thing that bothers me the most is when I go into a shop and sign in, I'll ask," how long do I have to wait, and the answer is almost always " 15 minutes" the problem is after years of experience I know that 15 minutes is really 45 minutes to an hour. I hate that, why can't these manicurists just tell the truth, why is it that they have to insult my intelligence by lying to me. I have never once in 25 years just waited 15 minutes, now I must admit that there are times that I get seen right away, but... If I have to wait, then it's always "just 15 minutes.
