Bench Press Bench Width

The bench press bench at my shiny new McCorporate gym seems narrow to me. My shoulder blades hang off the edges a little. My lifts are struggling more than usual because of it.

Am I being anal or is my gym doing me an injustice? What width should the bench be?

you can get some other bench there they may have thats bigger enough to fit your shoulder blades and bench press at the power rack with it.
