Was on the phone for 40 minutes before anyone answered my call, then waited 4 hours for the RAC guy to turn up. I knew what had happened to my car, and I knew how to fix it, but I just didn't have the tools with me. He spent the next 40 minutes faffing around, going inside his van, speaking to me about what he thinks is best etc. The only reason i'm giving 2 stars is because he managed to find a bit of tube to replace the broken one.
