Maharashtra State Road Transport Corporation [Msrtc] — the hotel at the stop charging more amount than mrp

Address:

411011

My ticket no is[protected]. I travelled by shivshai bus from kolhapur to pune on 27 may 2018.
The bus was halted at ashina hotel. The items like flavored milk, lassie were charged more than the mrp on the products. (30 rs in place of 25 rs.). When asked why 5 rs extra there was no reason by the vendor.
If the passengers are being looted why msrtc is making their authorized stops on hotels like this?
Is there any check by msrtc on the approved hotel stoppages?
