Couple A have a voucher for a very nice seafood restaurant that was given to them as a gift, it’s for £100. They want to treat themselves to a platter for £75 because why not.
Couple A have invited good friends couple B to join them. Couple A will pay for their own food and put the rest towards whatever couple B order, so around £15-20 after accounting for soft drinks.
Couple B have asked if couple A will use the voucher then whatever is left to pay is split between both couples equally.
Couple A think that on one hand it’s their voucher so their items are covered, but on the other hand they did invite couple B to join them.
Which is the best option?
