broken car

So this morning I only had about an 1/8th of a tank of gas and I don't usually go under a 1/4 of a tank so I stopped by the gas station on my way to work and pumped a full tank of gas. When I got back into the car and started driving I noticed that the gas gauge only went up to were it was before I got the gas. I was like what the hell. So when I got to work I turned the car off and back on again hoping that it would reset its self but it didn't. So I went to the bank and then the check engine light came on and the out of gas light came on. So I didn't want to get on the highway to come home and run out of gas, so I stopped at the gas station and I had to force $2 in the tank so it is full. So I guess my day off Monday will be at the dealership.
