Definitely, knowing the customer and whatever products and services that we can provide to them. Just let them kind of say, you know what, we have this, this, and this, and it's basically, you make it seem like it's the right thing to do for them. Let them have the knowledge that you are letting them know. For example, I've been in the automotive industry for a while, and I've always said, hey, with this fuel service that we are doing, might as well, let's go ahead and get those fuel injectors cleaned. Now that we're doing one service, might as well do the other because they go hand in hand, you know, and just kind of break that down. You're always going to get those hard no's, but 90% of the time, if you explain yourself correctly, they're going to be shooting for the extra.
