color coded bingo markers

So I was sitting at Bingo Wednesdays' night. I had my good luck statute, "Wilbur" and my coin purse of good luck out. I looked up and there this lady standing in front of my table looking at my Bingo markers. I thought this is weird. Finally she goes you have a purple lid on your green marker. I thought OK and I have a orange lid on a red marker, I was thinking she must be a little "Monk" like the TV show.

I just looked at her and told her nicely, it does not bother me. She just shook her head at me. I got looking around at the other Bingo players, I was the only one whose markers were not color coordinated. Wow and I thought they were weird ones.
