The notice reads: “Want Coca-Cola Classic? It’s one glass only.
“Based on new government laws, we’ve had to limit Coca-Cola Classic to one glass per customer.
“Still thirsty? Help yourself to any of our low-sugar fizzy Bottomless Soft Drinks.”
Under the new rules, any soft drinks that are low in sugar, for example ‘Zero’ alternative versions of most popular soft drink brands, can be drunk to one’s heart’s content.
I imagine that manufacturers of artificial sweeteners are in for a good time.

Possibly not related to the fact that /r/Lemmy dealt with Lemmy.
EDIT: Someone in that thread also mentioned that /r/lemmy2 was created in response, so it'll be interesting to see what happens there. If it stays up, probably unrelated to the subreddit being about Lemmy.
