The guest owes more than the desk may waive
"The guest owes ₹1,240, which is more than the ₹500 this hotel lets the desk waive at check-out." Collect it, discount it, or a manager waives it.
The sentence: *The guest owes ₹1,240, which is more than the ₹500 this hotel lets the desk waive at check-out. Collect it, or ask a manager: a login that can write off a balance can waive it.*
Why: the hotel's ceiling on what the desk may forgive on its own is on Hotel details (₹500 unless changed). Above it the decision is a manager's.
Do this: in the settle window, collect what the guest will pay and, if the hotel agrees to take less, put the rest under Discount (with who approved it) — that is not a waiver. Or have a manager open the same card, press Check out and waive it with a reason.
A second sentence from the same window: *A reason is required to waive a balance — it is recorded against your name.* Type why.
