Every individual could have different reactions depending their own context (for example if they ate or not before, if they are tired or stressed or not, etc.) but the most common explanation of this is that Allen drinks beer or alcohol more often than Greg and he developed tolerance to some of it's effects. Therefore, their metabolism works differently.
