I used to go there and get mani and pedi, and usually I remove them myself at home if I get gel (shellac) ones...one time I was too lazy and got them to remove the gel on my toe nails, which I had to dunk my feet in the bucket full of acetone for a few minutes.. Pretty standard procedure I guess, but then after I saw the lady pouring the used acetone back into this bottle in the back!? I was shocked. They do an ok job and the price is pretty reasonable (and if you pay cash they dont charge tax) but probably a good idea if you dont get the shellac removed by them..Im sure it wont kill you but I didnt feel comfortable about that.
