Okay so I thought of something that would be useful to me, and also those who are renowned for being a little too generous while out drinking.
The theory is an option/setting within limits, that is unchangable for 24(+) hours.
So for example if you’re going out on a Friday night, and you don’t want to spend more than £100. Rather than configure your daily spend limit, set Your ‘temporary limit’ (or whatever it could be called) mode on, select your limit of £100 and done. It will then countdown from 24 hours until you can change your daily limit. In theory this will stop you going and upping your limit to accommodate the next round(s) of drinks, and encourage you to spend it more wisely.
Obviously this could be useful for things other than nights out.
Anyone else think this is useful or should I just learn to rein it in while I’m out partying? 
Also would be interesting to give this feature a cool name. night out mode? Party mode?
