Maybe the red squirrel drank too much of their beer and went mad? I went there once and bought/filled two of their plastic bottles with beer. Although it looked fine going in by the time I got home a couple of hours later and drank some I reckoned it had gone rather flat. Having had a similar experience with another place's take-away beer [https://whatpub.com/pubs/MCH/3937/local-markyate] it might just be an issue of using plastic bottles, not glass ones?
