Operation Airhose- Delta Flight Crew shoeplay slide

I saw this group of Air-hose-tesses from delta, on a layover between flights. The one i focused on already slid her heel off and was dangling the heel on the crossed leg. She was doing some knitting. There was another FA i focused on, she also was sliding her heel off occasionally. The 3rd FA was doing some shoeplay too, but she was blocking my view with her suitcase. The knitting Air-hose-tess put on a show...i followed them to their gate when it was time for them to go, they had to wait for passengers to get off the plane before they could get on, so they sat again and waited and i caught some more shoeplay under the chairs at the end.
