Lol..thats pretty funny, when I was in college I would work winter break and summer as a laborer for a masonry company, and I was in the same predicament, we had 2-15min breaks and a 30min lunch and I would always bring healthy lunches and have protein bars and shakes, nuts, fruits....and they would all give me shit, but I didn't give a fuck.....they would also try to work me extra hard so I would be too tired to workout after work, but I always would (lol).....dude it's just part of the gig, when you do labor like this everybody busts eachothers balls, fuck what they say bro, bring some nuts, fruits, shakes, bars whatever...
