Italians better than ice cream shops. Warehouses (IMO, and most others) are total crap, lol. The HLP kept both lvl 10 warehouses b/c of the time invested in it. But the time invested could have been invested MORE wisely, understand? T-shirt stands are a win/win b/c of the tiny spots they fits in and also the income isn't shabby at all.
Pawn shops are decent but quickly become overlooked in upgrading things b/c they aren't worth it after awhile.Gas station (IMO) also aren't worth it at all. I sold my two lvl 3 gas stations b/c i would never upgrade them again and needed space for my Empires(:
