Instant Karma

I think instant karma is real- I've had quite a few run ins with it and most recently ( yesterday ) was at old navy. I was in line w/ my mum and this nice lady asked us "May I go ahead of you guys? I have to pick up my kids at 7:30 ( it was 7:20 at the time)" So we said yea ofc! you can go ahead. Literally 5 seconds after the next counter was open, my mum had some things to check on her account so it took a bit longer but somehow we finished b4 the lady that wanted to go in front of us. I guess it's karma for letting her go ahead? Maybe just a nice coinky-dink!
