A Catholic may eat meat when that is all that is served. Even in Lent.And of all days, they choose Friday to serve the pork. Even Catholics would take offense under such conditions (throughout most of the year, enduring the unjust punishment would suffice for Friday penance, but abstinence is still required for Fridays of Lent).
A prisoner doesn’t have to forego what they are given.The syntax was unclear. I was under the impression that the meat ration was given in addition to the standard rice soup and bread ration.
