Menards of marion,iowa purchased new snow blower,added gas,gaspoured back out of tank.tried to return they would not take back because we put gas in the tank. how else were we supposed to start it? marion, Iowa

Purchase a brand new snow blower for our son for christmas on december 30th while we were visting at the menards in marion,iowa. After hooking cables and handle up he put gas in it to use it and the gas leaked back out all over the garage floor. He let the gas finish draining, put the snow blower back in his truck and went back to menards. They informed him they would not let him return the snow blower because he put gas in the tank,  how are you supposed to use a gas powered snow blower if you do not put gas in the tank?  Sad part is I used to work for Menards in Ottumwa, Iowa I now live in Michigan were there is talk of menards putting stores soon. You can bet I will not shop there and when i get done no I know will either.
