Yeah that's what I (finally) understood it as. Bob has bought 4 tickets and 3 have gone back to the club to be gifted to someone else to use. Bob was then told he could go and, under normal circumstances, so could the 3 others (presumably the club have thought all four were in a family or a friends group with Bob) but with the restrictions groups going and Bob having explained the situation, it's either Bob goes himself or the three others go (assuming the other 3 tickets he handed back tot he club have gone to a family). Not great but given the restrictions that's what needs to happen although Bob, as the main ticket "holder" should really have been given first shot given he paid for them.
