Weird situation in Paris

So while in Paris, this guy yells at me in French while in his car.

"Hi. Sorry, I don't speak French." (Me)
"oh... Do you know where the Louvre is from here?" (guy)
"Oh. I have no idea. This is my first time in Paris. I'm kind of..."
"Wait, what else you speak?"
"Um. I speak Spanish" (Said in Spanish, conversation continues in said language)
"Ah! Espanol! De donde eres? No eres Espanol verdad?"
"No, I'm not I'm from California."
"Ah, California. Are you Mexican?"
"Yeah, yeah I am actually. How'd you know?"
"Well, you speak Spanish and you live in California right?"

Anyway, the conversation continued for a while with me being suspicious of this guy's behavior and niceness (I'm in a touristy city and this guy had a mustache and sunglasses, so my suspicion was not unwarranted) until at some point, he shared with me that he worked for Armani, and, because I'm from California and he's such a nice guy, he wanted to give me a free promotional suit so I can "get the ladies at the cabaret" (or something to that effect).

Guy let me feel the cloth of the suit and put it in my hands, to which I was thankful, but kind of afraid. Should I accept this guy's offer? It was then that he asked me to do a slight favor for him. Showing me his empty gas tank, he asked if I could spare him maybe fifty euros to fill it up.

I wasn't sure what to do, so, rather than extend the possibility of some kind of harm or theft, I handed back the suit and thanked him but said I couldn't go through with this kind of deal.

What the fuck? Any ideas what this guy's deal was? I can't have been paranoid in my suspicions, but I wonder what the goal of his ploy could have been. Any guesses would be appreciated.

Besides that, going to Valencia this weekend. I know very little about the place other than that they have a dialect that isn't Spanish, it is the third largest city, and apparently they have delicious Paella, which is a very creative dish, what with the rice and the meat and stuff.

PS: Holy crap. Stephen Colbert might actually win this election.
