This fast food outlet completely lacks business ethics

This fast food outlet completely lacks business ethics. It advertises specials and when the demand rises it conveniently makes its App unavailable. When the App does work it's a load of nonsense since the designer/s think that ordering food is the same as playing video games. It times out before you can even complete your order. This App is not worth having on my phone. I'm deleting it immediately and this ********* company will never again see another cent from me.
