Nandos dry chicken

I drove through bryanston nandos I requested for extra sauce on everything I bought,when paying I reminded them and on collection I told them as well and only to check and find the meal dry,I then requested them to put extra sauce and they took the packaging and brought the food and the guy said he put it himself,only to reach home to find a bit of sauce,um so angry that I won't go to that nandos again,I think it's unfair coz u pay a fortune to enjoy the meal,and now um enjoying embarrassment,
