It's the frog in the hot water concept. Most CF don't start of massive favours. First it's small, then it gets larger and then people have invested time into the relationship so don't see a way out as this is the way it is now. This is amplified if in a group of friends if ones always asking and others see not say no.
Friend of mine has been asked to babysit new born up to toddler multiple times (never reciprocated) so the couple can have date nights ect as the friend loudly complains they are alone with no help (which isn't true). Clean her kitchen and generally tidy up whilst looking after baby and the house is a bomb sight
Used her washing machine and (all of her laundry stuff (laundry power and softener) multiple times and finished it on several occasions without telling anyone. Not one bag of clothes, I mean 4 people's worth of dirty laundry for a month so about 8 bags each "go"
She's one of those people who host a dinner party and asks everyone to bring something and doesn't make anything herself . Then complains when it's not the right bread (we only eat the Tesco's finest range) and actually produces a list of ingredients they need and any extras they are missing just for general day to day usually extra £20 of items that aren't for dinner party.
To fix their car for free (her husbands mechanic) and to only pay for parts, then once parts were ordered started questioning the price of the parts via google and asked for broken down invoice from each of suppliers, when that wasn't enough she then said they didn't have the money for the parts (my friend husband had paid upfront for them) her friend then said can we pay instalments, paid once and never paid again and complained the car could only be worked on weekend and they needed it ideally the day after it was given to be fixed.
List of toys to buy for kids for Christmas and where they can be purchased not cheap places either £40 being the cheapest 😵💫 and to return the favour my friend children got free bag from a magazine.
I actually don't know how she puts up with it. The friend on question tends to fall out with people a lot when they stand up to her, so my friend feels sorry for her and is completely oblivious
