Quality of food compromised with specials

Spur has a monday special whereby if you buy one burger you get another free, my husband and I decided to have the special, however the quality of the food was really comprised!!!<br> <br> My burger had a funny taste as if it was rotten, i even got sick from it and had a runny tummy!!!<br> Waited forever for a manager and ended up just paying our bill and leaving<br> <br> The quality of the food should not be compromised just because there is a special. Really disappointed.<br> <br>
