Ian Reisner calling Luis 'Ricky Ricardo'.
Ian Reisner was quite the miserable little jerk.
The "Ricky Ricardo" stuff wasn't funny and was nothing short of belittling to Luis. Here's a gay guy, who presumably knows something about being ridiculed for being what he is, gay... ridiculing Luis for being exactly what HE is... a straight Puerto Rican guy.
Then there's the gay comments he was making which were clearly making Luis uncomfortable. Reisner knew it, he just didn't care.
Finally, after an agreement is reached about Luis' representation, later in the show he springs the fact that he has his agent's license and wants 50% of the sales commission. That wasn't the agreement.
What an ass.
But Luis screwed up too. After Reisner called Luis "Ricky Ricardo" a few times, Luis should have told him "my name isn't Ricky Ricardo, it's Luis and I'd appreciate you calling me by my name. If you can't remember it, I'll write it on a piece of paper and pin it to my jacket so you can read it. Let's talk business without further mention of anything gay or straight. If you can't do this, I'm out of here".
Luis is making good money in NYC and he doesn't need to take any crap from that punk ass Reisner.
