So I recently had email correspondence with McDonald's enquiring about if they use different BBQ sauce in the chicken legend to the BBQ dip. They confirmed to me that every BBQ sauce used in McDonald's is different. Now as a fan of the BBQ sauce in the chicken legend I would much prefer this sauce as a dip.

Now not only is this a personal preference for myself but even just from a logistics point of view it would make more sense to get all BBQ sauce from the same supplier. 

This is also means with the current set up that whenever you order a meal with BBQ sauce in it, you wouldn't be able to add extra yourself without ruining the flavour. In my opinion this should change.
