But, ok, yeah, I'm sorry. I'd perked up and replied to parent because the "2 standard unit 20ml limit" as "safe" seems to show up in a bunch of studies, and interpreted "2 drinks" as that. But if he meant US standard drink that would be a 1.7*2 units (or 2 5% beer bottles), which is a bit harder to hit (but also firmly in unhealthy territory). That said, as another person noted, you can blow through that with a high ABV craft beer really easily (or an overly full glass of wine).
