Throwing away your trash

Is throwing your garbage on your way out of the restaurant helpful? Not necessarily, according to Morrone. He recalls instances where guests would toss their trash into garbage bins, but the problem was that recyclable material would often be mixed with food scraps. This meant employees like Morrone had to sift through half-eaten Big Macs and warm milkshakes to separate recyclables from non-recyclables.
