What should be put in the bag? [br] [originaltext]W: I forgot to tell you. You

W: I forgot to tell you. You can’t throw away the bottles. Here, just put them in this bag.
M: O.K. I didn’t realize. I threw a water bottle away earlier this morning. I’ll go and get it out. Should I put the glass bottles in here too?
W: No, just the plastic ones. We have to pay a deposit on the bottles every time we buy a drink. Afterwards, we take them back to the supermarket and get our deposit back. It really adds up.
M: Oh, I thought it was for recycling. Well, I guess this big bag of bottles must be about four or five dollars, right? Do you need some help in taking them outside?
