Fans already do that. As anyone who attends games can attest to.Fans committing to doing their eating and drinking at independently owned pubs and whatnot outside the stadium would actually be an extremely effective way to target ENIC while supporting the club as an ecosystem and community broadly considered.
Fans boycotting food and drink inside the stadium has ZERO chance of happening on any wide scale so the idea it's any sort of protest measure is just fantasy.
