AP Anti-disguises

I'm doing electrical work at my local casino and I pop in for some blackjack every now and again (I can get to the floor without going through the front so no ID checks. Do you think extremely bright yellow hi-vis makes an easier target for security to watch what you're doing or do you think they'd brush the player off for being a lucky dumb construction guy? Or do they determine who to back off purely based on how they're playing. I'm nowhere near an AP right now, just applying BS and imperfect counting skills.

I'm only buying in for $100 during lunch time and playing $15 tables but I've been going positive each session with perfect BS and not hiding my betting strategy. What's security probably thinking?
