I'll never forget how I felt when I lost £150 in a Pie Factory 1 [2x nights at £75 a night] - bear in mind I was on UNDER £40 a week at that point, and hopefully you could understand. You reach a point when all you do is lie in bed at night and think 'why?' - I could have done anything with that cash :
a) bought something useless but at least had SOMETHING,
invested the cash and made 20p interest a year or something,
c) donated the cash to charity and at least known I'd benefitted someone, or
d) paid off some stuff I owe to certain credit people [*ahem* Argos Card *ahem].
Now that I think I'm finally free from machines [about 6 months and no machines], I'm so much happier - ANY machine - modern or not - £5 or £2000 can take £10 to get ANY return, which is something some people seem unable to get to grips with.
'78% payout' means that over the £1000s the machine takes in its period on site [I took £700 from a £15 AWP in a pub on 20p play recently], that the machine keeps £220 of that [or close, with about £1000 in, depending on how played, they'll be close to percentage] - and that means SOMEONE has to lose £220. At least it won't be me now!
I've given up on the GGs as well [following 2 bets on Christmas eve, 2x50p E/W on 20/1 shots on the Virtual races, one coming 1st and one coming 2nd for a £14.50ish profit for a £2 stake].
Theres better ways of having fun than putting up money and suffering the mental torment that follows when you inevitably lose
