That anyone who uses a toilet outside their own home is 'disgusting' or must have medical issues, because otherwise you just wait until you get home.
The answer to DHs or teenagers that hoover up all the snack food or even ingredients for family meals the day it enters the house is to 'just buy more' because not wanting people to eat six bags of crisps a day, or needing to stick to an affordable budget is 'controlling' or 'being mean with food and an attempt to starve the poor man in his own home'.
No-one is ever selfish or fussy, because they will only eat at the blandest restaurant in town, they have 'sensory issues' and must be accommodated without question.
Rules for eating out: You must always tip, even if the service and food is diabolical. If you cannot afford to do this, you shouldn't eat out.
You must always agree to split the bill even when you can't afford to. You must not only order one main course and a soft drink, even if that is more than enough food for you and you don't normally drink alcohol anyway. To not have three courses, wines and cocktails is 'being miserable', 'spoiling the atmosphere' and 'not joining in'. If you can't afford to order food that you don't want, simply to be sociable, you should not eat out.
You must never ask to share a pudding or side, even with close friendsb or even your partner. Even if you only want about 3 chips, or a tiny taste, you should order your own.
