Yes, my friends and I systematically make bets. For example, not to be late for a meeting, whoever comes last pays for coffee, this has already become a tradition. It is also connected with sporting events, if the forecast does not come true, he buys beer for the whole company, or if it does come true and he hits the jackpot, the beer is also at his expense. Such disputes are more about entertainment and not about profit, it is more interesting to spend our time together since we do not see each other that often anyway and this adds its advantages for seeing each other a little more often.
