For a lot of guys, 4 houses is a big day. If Junior is available, you should bring him with you. 2 guys can do things a lot faster and more efficiently that 1 alone and it gives you more opportunity to upsell. Not talking about scamming the customer but let's say you are there to do the carpets only but they have upholstery that needs cleaning. If you are by yourself, often you will pass on that because your day is full already. With 2 guys, you can knock it out faster and possibly make more money per job. I find myself leaving money on the table because I am too busy in the moment.
