Rescue me

I was driving to Newport velodrome this morning and got a flat tyre on the M4.
Wheels nuts removed, car jacked up and spare wheel ready to fit.
Grrr... The wheel will the flat would not come off. So, a call to the RAC to come and help was made.
Double Grrrr... they took 2 1/2 hours to get to me. By the time they arrived I had missed the session so just drove home.
