Friends Alice, Betsy and Charlie are going to an event together. Charlie mentions his friend has a spare ticket for the event and both Alice and Betsy express an interest.
Betsy frequently buys tickets from reselling tickets and has lots of contacts within this route. Alice doesn’t but is happy to buy hers online from a legal reseller.
Charlie then says that his friend’s ticket is £50 and Betsy immediately says great I’ll have that. Alice sees the message 5 minutes later and says that she’s also keen to go - is there another being sold? There isn’t and she expresses disappointment as she has seen messages on reselling sites selling the tickets for £100.
Alice sends a slightly irritated message to Charlie saying that she wishes Betsy had told her she was going to get the cheap ticket - as they were both interested and maybe they could have split the difference.
