And I sat and did not understand who to blame: myself for a weak laptop and the desire to press this button.
Or the creator of the site for the fact that it could not work stably, Even on the weak equipment of the gambler (me).
I understand that most likely many will say that I am to blame for this situation, but shouldn't an online casino stop accepting bets if it sees that the "gears of the game" are not spinning as they should? After all, this is a game for real money of the gambler.
I like the fact that you actually specified that you used a old weak laptop to visit the casino site. The thing is, AFAIK, these websites contains so many activities, and they where literally designed to work in their best and most efficient way despite the loads. If you kept clicking or triggering what can affect your deposit despite knowing the problem on ground like the sudden froze, then it is more of your fault. Because your computer was weak like you pointed out, and there was a chance that the first spin actually triggered, but your computer or Internet connection couldn't keep up.
I've come across similar issues whenever I use a betting site, though mine is as a result of poor Internet connection. I'm never in a hurry to click anything. I just exercise patience, and allow the whole the to return to normal before proceeding. I doubt if those with fast connections and smooth running computer faces issues like this.
