Modern Nails

I have had a mani and pedi yesterday, regular Opi nail polish. By today 7 nails were chipped with one half gone. Apart from taking a bath and washing my hands as normal I didn't do anything that would have caused this. I visited the salon at 9 to be told to come back in an hour. I mentioned I'll be there after 12. When I arrived again, the lady who seems to be the owner/in charge told me that regular nail polish chips quicker, to which I replied that surely it should last longer than 18 hours ... she said they'll fix them if I waited an hour. Very poor service. I won't be visiting this place again!
