I try not to leave a mess while I shop -
HOWEVER -
if the bolts of fabric are wedged in so tightly that I need a prybar to make enough space to put the bolt back on the shelf - I will either leave the fabric leaning against the shelf or laying on top of the bolts.
I don't have the upper body and/or arm strength to be able to shove the bolt back in.
Or - if/when I try to pull one bolt out to look at it - and five or six more come crashing down along with it -
I realize that shelf space is probably limited - but I will just walk away when that happens.
