Food and disinfectant don't mix.

My wife and I went to Design Quarter yesterday, The food and service was very good, including good value. However it was spoilt by the staff washing floors with a strong smelling disinfectant whilst patrons were eating. Breathing in that strong smell and trying to enjoy the food was a big no for us. We complained and moved table but that didn't help. We understand the need for cleanliness and hygiene in a restaurant, but please do it when patrons are not eating.
