I just got gel nails for the first time - I bite my nails and wanted to look professional for my graduate school interviews. The entire process took over 1.5 hrs, but mostly because the person doing my nails kept answering the phone and was really distracted. They charged me 42$ and I left a 6 $ tip. Well, it's only been 5 days and half the nails fell off today ! I haven't really done anything, just have been carrying on with my daily activities. I was under the impression that these will last me at least a couple weeks, not 5 days ! Is this normal or did the person doing them do a bad job ? What should I do ?
