Cover art for Store lyrics by Mountain Goats, The

I agree with a couple of things the people above this post have said but i don't think there has been an accident in the store, i think that the protaganist has had one of his friends commit suicide and he's trying to drown the memories in alcohol so when he goes to the store to buy some booze he passes out in the alcohol section "amidst all of the can and the glass and the chrome" and dreams about them and how he last saw them.

To the link with "Your Belgian Things" I feel that only that line fits with this song as my opinion of that song, which might end up on the comments over there, doesnt follow a suicide. Although following that idea the song still makes sense.
