media criticism

I finally unpacked from last weekend's NCMR, and unloaded the special NCMR tote bag. I've learned from the past couple conferences I've attended that tote bags are apparently a necessary part of every conference. Am I being an ungracious a**hole when I say I find this ridiculous? Sure, tote bags are helpful in organizing all the conference materials and other items handed out at workshops, but don't people bring their own bags?
