I never really sit in at McDonald's in Aberystwyth because quite often it's full of teenagers just dossing. So normally go through the drive through. Now I love a mayo chicken but with cheese. I've always ordered it for as long as I can remember. On one occasion a couple of weeks ago the lady said she can't allow me to have it because there's not an 'extras' option on the till. Well I'm sorry I have since been to another Mcdonalds in Telford who served it without any issues and surprise this evening I went to McDonald's In Aberystwyth & had my mayo chicken with cheese.! Some staff either need extra training or a good bloody ear full off the manager. How bloody lazy!
