The clever old Barbican has launched a free app with which you can order your interval drink in advance, from 48 hours earlier to 30 mins before the concert begins. More info here. And you can download it here. Well done, chaps. Fast may this spread.
It's not a minute too soon - we all know the score. You have a 20-minute interval. You spend 15 minutes of it queuing up, another 2-3 processing your drinks order (finding, pouring, paying), and then you have 2-3 mins to down the liquid before you go back into the hall (being a classical audience, you are expected not to take said drink in with you). Alternatively you might have arrived early to spend 15 mins queuing before the concert to order your interval drink. And you can't help wondering, having been to sensible places like Germany, why we can't do as they do and have a whole rack of ready-poured helpings of the most popular drinks - red & white wine, beer, orange juice and water - so that people can just pick one up and hand over the cash pdq, which would save person-hours, aggro and the usual headache of having to choose between a drink and a trip to the loo.
Speaking of which, please can someone invent an app to create faster access to the Ladies Room?
