What's your 'just missed out' story but from avoidable circumstances

My wife just walked in as I was playing roulette on my phone. She gets funny about it sometimes and CBA with a moan and not only did my number win but a boosted number!

20p x 36 x 40 = £288 I missed out. A lot of money for me 😢 not said anything. I won £34 of free spins and was just gambling £4 of it btw 😂

She doesn't even moan that much she just sometimes pulls a face like I'm snorting coke

Disclaimer: my wife is amazing and I'm lucky to have her. Just frustrated.

So what's your story and for it to be avoidable i.e this is my fault, I shouldce just played.
