My staff demanded No-Journey certificate from the TTE who asked him to wait. At 01:00 in the night, he cam back and asked whether he wanted full seat or certificate? if full seat, he will not issue certificate or if certificate is required, he will give him only half of the berth and on the remaining half, will set somebody else (we all know the rule that if an RAC passenger does not report, the remaining passenger gets confirmed on the same seat and other rule is that, in running train, no RAC is allotted).
And ultimately, the required certificate was not issued and hence, no refund.
