so I'm happily eating my pistachios on the train and some woman comes over and says 'could you put them away my friends allergic' I said 'oh yes of course' started putting them back in my bag when she adds 'to be honest you shouldn't eat things like that on trains anyway' turned on her heel and stalled off. They then spend the next 10 minutes throwing me filthy looks. Now I understand nut allergies can be fatal and was prefectly happy to put them away, but was I bu eating them in the first place? Surely you cannot assume every where will be nut free and especially on public transport at 4 in the afternoon there is going to be risks?
