LPG crisis affecting PG food - what to do?

My PG used to serve full meal - Roti, Sabzi, Daal, Rice, and Salad.

Now, stating the LPG crisis, they are only cooking either roti sabzi or Daal chawal. Whereas they are willing to take the full rent.

Isn't this unjustified? I know there is a crisis (more created than real). But, shouldn't they reduce the rent, because they are not serving the full meal they are supposed to as part of the rent?

Shall I deny a portion of rent? Anyone facing similar issue, what did you do?
