Indian Railways — tips forcibly taken by food serving staff in bhubhaneshwar rajdhani express

The people travelling in bubhaneswar rajdhani, whether 3ac, 2ac or 1ac, all are facing the gundagardi of the fooding staff who are asking for tips forcibly. I have travelled on bubaneswar rajdhani many times and faced this misbehaviour every time. But this time, their gundagardi has crossed all limits. I think the railway department should put up notice in the bogie that whoever ask for tips should be removed from his job. Necessary steps need to be taken so that such incidences are stopped in bhubhaneswar radhani.
