The best restaurants serving Fast food food in Hounslow Heath Hounslow London

Walked in and ordered my food (no problem) whilst waiting I watched the man that served me casually walk up to the bin and spitt into it, he then just casually wiped his hand across his beard and mouth before making the other customers burger and handle money without any attempt to wash his hands, Another member of staff came out from the back and also preceeded to wipe his gloved hand across his mouth before handling food and Another member of staff was walking around the back of the shop bear foot where the food is prepared, I won't use this place anymore as the staff hav have no idea about basic hygiene.
