Sneeze and you’ll miss it
Sorry to hear that. That's really awful. I didn't notice any cooking demonstrations with egg when I went. Hopefully it was because they learnt from it. As I'm sure you know, the tickets include the Vegan show too and so I'm really surprised that a exhibitor chose to cook with egg. Anyway, hopefully they won't be there this year and the exhibition clamps down on it. Although the actions of one thoughtless individual has probably put you off for good. Maybe give them a call if you do fancy it, to help ensure that any live cooking takes your son's and other people's allergies and life choices into account?
My son has quite a few allergies so thought this would be a safe space for him. Nope, they were doing a cooking demonstration and cooked eggs of all things, to which he has an airborne allergy. He had an anaphylactic reaction and ended up in A&E.
My wife has an allergy to spending her own money, but not to mine
This year it's in the Excel so a bit to far for me. However, not a bad show combined with vegan show.
