Are six 0.33L Beer a lot for a night?

I am not sure but my friend says it was a chill night they only had six beers. Usually they drink way more, so he really meant it was chill.

Is that really not a lot of is that a lot? In total it’s 2 Liter beer in a time span of 5-6 hours.

What you guys think am I just overreacting when I say thats still a lot? They all laughed at me and said it’s not a lot.
