How Long Should a Professional Manicure Last?

I got my nails done last week and the polish is already wearing off at the tips of the nails.

I don't do too much that is strenuous: Mostly the equivalent of office work. I don't even do dishes. My home manicures last longer.

Maybe I am overreacting. I just checked and I was given the classic manicure which is not the full service manicure. But I still think it should not look this bad after one week. When I figure out how to get a good picture of them, I will show you.
