Big Bazaar / Futurebazaar / Future Retail / Hometown — staff behaviour at billing

Address: C 9 A Gulag bagh, Fatmaan Road, Varanasi, Uttar Pradesh, 221003

Abhishek maurya a staff at sales at big bazaar sigra varanasi disturbing billing and getting people known to him getting billed out of line. On asking him that this is wrong he started shouting and misbehaving that we are staff and our billing is done first.
This is happening for the 2nd time since the last 1 month. And above all had the atrocity to say "k complain karna hai to kar do".
We have been waiting in line for more than a hour and staff people get billing of their known ones out of turn and when questioned get abusive too.
Please look into the issue as we being regular customers have been facing such issues at the outlet continuously.
