If your name is not Jim Chochola and if you have nothing to do with Membership, you shouldn't have moved the envelope behind the bar. Twice now a folder labeled something to the effect of "Membership paperwork for Jim Chochola" has disappeared along with members' paperwork inside.
I will find a better, more fool-proof place for it. But, if you know the whereabouts of the previous two, please let me know!
