Catering Services At Shatabdi Express — catering staff misbehavior in lucknow shatabdi

I travelled in lucknow shatabdi on 24th jan18 and i asked to catering staff mr. V. K gupta can i get another omellete then he denied to have another. But suddenly served the same to other passengers multiple times then i asked why u are serving to others then he said it was unavailable. And after that i realised him to treat equally to all passengers without any partiality or any extra fare.
And i am requesting to irctc not to recruit such kind of catering servents.. And take action for future references..
