I often get gas at the same gas station, as they tend to have lower prices and I can use it as an excuse to stay away from the office a little longer during lunch break. At this gas station, they have vendors who sell different cleaning products for cars. Their pitch is to walk up, get you to allow them to spray some of their exterior cleanser on your car, and then discuss their other products as they buff out the cleanser.

Anyways, I had gone out to lunch and then went to fill up my tank. As I pulled in to an open pump, a woman drove up on the opposite side. She was absolutely gorgeous, well-dressed, nice car, etc. The vendor guy noticed as well, and made a bee-line over to her.

He immediately opens with: "Hi, have you heard of our product CleanShitOffYoCar?"

She replies immediately: "No, and I'm not interested."

Him: "Well, do you even want to know what it does?"

Her: "I don't care."

She had effectively shut him down, physically turned around, and started actively ignoring him. She was also extremely icy in how she had responded to him. He stood there for a minute as I smirked and tried not to laugh on the other side of the pump. Then, he had an idea. He walked around the pump to where I was standing...

Him: "Hey, have you hea-"

Me: "Yes, and I don't want any either."

Him: "Do you even know what it does?"

Me: "Sure do! Had a demo last time I was here. Thanks, though."

Now, normally the vendors just walk away at this point. But this guy... this guy knows what to do. After a moment's silence where I am selecting what type of gas to pump and looking at him with a slightly bemused expression, he leans against a pole next to the pumps and pulls his phone out, pretending to check his stocks or something (doesn't really matter what). His tone immediately switches from business to casual.

Him: "Yeah man, just got back from a work trip to Dallas!"

Me: "Oh, really? How were the tornadoes?"

Him: "What? Uh, no, it was just for product training and development." he obviously doesn't get the tornado joke :(

Me: "That sounds cool. So like an industry-wide convention?"

Him: "Yeah exactly. In a few months, I'm gettin' sent out to Puerto Rico!"

Me: "That'll be awesome! Nice little summer vacation!"

Him: "Sort of. We won't have too much time to ourselves. We'll be there for 5 days, only one for fun."

My tank finishes filling at this point, and the conversation kind of trails off. He takes a couple steps back towards the woman and her car, and feigns surprise at something he sees her doing.

Him: "Wait, does your car take diesel?!"

Her: "Yeah, why?" already a much warmer tone than before

Him: "blah blah blah" he bs's something about the hoses, I didn't really hear the whole thing

Aaaaaand, he's in! He started a conversation while I went in to grab my receipt, and they were still talking when I drove away from the pump.

He got blown out immediately, recognized it, and then used the conversation with me as a pivot to transfer comfort and value.
