to comp or not to comp

I am a beginner counter and have several casino cards from my pre-counting days. Am not a high roller and in the past(not counting) have enjoyed a comped meal pretty much every time I went. Recently have played
14+ hours blackjack without using the card and accumulating any credit.
14+ The
reason being, is a fear of this being used as a "tracking device" if I am suspected of counting. If personal is suspiciuos, could they possibly post an "alert signal" for future observations. At future visits could this signal the pit bosses, or eye in the sky, to watch my play every time the card is swiped. After adaquate time of watching, identified with my card, they could conclude I am a counter and possibly lead to barring. If they don't have this card my play is hidden by short visits at a time on different shifts, hopping around at different tables. It just so happens that I have been on a big losing streak and have handed the casino plenty of $, thus not recognized as a winning counter. Having a comp for all this play would've been nice, but I'm thinking long run. Is my thinking of not using the card a good idea? Or am I just being a little paranoid, missing out on meals and/or rooms, and looking into negative outcomes too much? Any opinions, experiences, guidelines are appreciated.

IMHO:

If you have played at a casino alot, the chances are that the PCs recognize you already, especially if you camped out for 14 hours. If you were to change your habits, ie: no longer asking for comps, and they remember you as a comp whore, then it may raise suspicion.

You may choose to save that casino as your lodging/dining casino and continue to play for small potatoes, watching your spread and bet size, and go for the bigger bucks elsewhere.

I just came back from my post office box. Today I had $700 in cash coupons. Sure, you may get backed off sometimes because of tracking. If you are afraid of this then discontinue getting rated when you hit a specified net win, or start getting rated under a new name when you hit that level. But comps are simply too much to give away. I think comps are most important for light green players. It can be said that they are really trivial for heavy black bettors (although I won't be saying that) and that red chippers don't earn much anyway. But light green players usually can earn enough in comps to cover their meals and lodging, which could be two or three hours worth of ev for them. If you try to coordinate your trips so that you visit cities at times that maximize your cash coupons it further enhances the value. I think comps can easily add up to 20% of your lifetime return. For those counters who end up net lifetime losers, and there are quite a few, the comps are the only thing you'll ever get.
