For in eating every one taketh before other his own supper: and one is hungry, and another is drunken.
One taketh before other - the rich "before" the poor, who had no supper of their own. Instead of 'tarrying for one another' (1 Corinthians 11:33; 1 Corinthians 12:21; 1 Corinthians 12:25).
His own supper (Philippians 3:19). "The Lord's supper," the spiritual feast, never enters his thoughts.
Drunken. The one has more than is good for him; the other less.
