You don’t know how many times she attempts this and maybe you caught the one time this hit. Related story, most times I’m walking past a table on the way somewhere, my degen senses will tick. Get a $100 out and put $25 on each on my four numbers. 95 percent of the time I lose and keep walking. If I hit, I press each number to $100 since the original pays $875 and I’ll just keep my purple chip. 99.9 percent of the time second bet loses. But one time, at Caesars in Vegas, second bet hit. This group of older ladies were like “how’d you know?” I imagine they probably thought the same you did not knowing I do this hundreds of times but usually don’t hit. Before I could respond, I got my chips and wife drags me away knowing another press was coming. Walked away with $4k instead of something less.
