I read that more as they want the club to find a way to reduce the queuing times at half time, so that their fans can do those things during the 15 min break rather than (as you have seemingly read it as) calling for the break to be extended
Exactly like we had with our fans complaining about the queues at half time when we first moved in to the Amex and how long it takes to get served
But it doesn't say the catering situation needs to be addressed (as our fans do) or that the queuing needs to be looked it. It says, quite specifically "The 15 minute interval needs to be addressed". It's a strange wording for your interpretation.
And it's also hard to know what the club can do within 15 minutes anyway (as the Albion know all too well)
