I'm not accusing anyone of being an alcoholic, I just know what I would be doing if I had a mandatory 2-hour lunch every day! And it's not eating (probably not as much as I do now)
EDIT: On the chance that my ambiguous grammar has got you tied... in the right order, I would be a bit slow for an hour or two in the afternoon, after having three or six cervezas.
Wait, how does extending lunch by an extra hour push closing time by 3-4 hours?
