Lol... we actually tried ordering one of those drinks each, but they aren't legally allowed as apparently the 5oz. Liquor is more they're able to serve to a single person at a single time.
Though ya... guess they aren't all that environmentally-conscious, wasting the plastic of those two unused straws. Bastards. :-p
So is that a no on being my friend? kinda vague. But I agree probably for the better on the alcohol limit otherwise people would get super drunk. Looks like you were drinking Watermelon margarita if you are near a On the Border. They have fresh squeezed watermelon ones.
