Srilankan Airlines — i'm complaining about the tray tables in economy class

Address:	11500
Website:	Sri lankan airlines

Whenever i fly from colombo to karachi in economy the tray tables are very dirty. Looks like no one is cleaning them which is very unhygenic. The staff doesn't pay attention to it also and they are sometimes mean like not responding to you when you need something. Please look on to it and make sure the tray tables are clean. I will be giving positive feedback if they are clean next time. Thank you.
