As the title suggests. Who pays what in this scenario.
A lends an item off B to be used during an alcohol fuelled 21st birthday party. C breaks this item while drunk. B tells A item cost £100 when it was bought, C gives A £100 to order a new one to give back to B. Item is no longer available and closest one found is £150. Should C cough up the extra £50 to buy a replacement or has C payed enough as that is what the broken item was worth.
