I ask the sacker to keep the bags light (and milk in a sack) so I can distribute the weight for two trips up the stairs. I don't know what I'll do if they force me to go to personal sacks. Well, nothing, I guess, except vote republican twice in November.
There's a natural food store here I sometimes shop at, but the first time I was amazed that there were no, zero, null, nada bags. I was at a loss until I realized they had great big bins full of cardboard boxes of every which size which their products come in, so I toodled my cart over there and filled two boxes with stuff and brought it home that way.
I'm all for saving natural resouces, of course, but sometimes these greenies start to get to me.
