Don't abuse retail and hospitality worker just because you're frustrated or having a bad day. They are people too with thier own thoughts and feelings, and the your words and actions can wound them deeply and they may remember the your cruelty for the rest of thier lives. If you want to to be a shit cunt to strangers than you can fuck off then.
Also, while casinos and more so pokie room are depressing places full of figurative zombies, desperate sorts, and fools. The air is stagnant and permeated with the stench of body oder and stale beer, and the machines sing out with pings, sirens and gongs so loud the one can barely hear thier own thoughts let alone the angry screams of the man next to him who just lost half a week's pay in half an hour. There's only one redeeming thing I can say, and it that if you're one of the extraordinarily rare and luck few and have the self control to not play that one additional $20 slap. You can take that that $25,000AUD jackpot home with you. Should be so lucky(probability says it never gonna happen, though).
