Sick to my stomach

I get 30mins lunch and took the time to Go grab lunch at Spar In Obz <br> A chicken Burger I get back to work. Open up the burger and the lettuce are brown and soggy the tomato was so old it soaked the bun which as soon as I opened it up I got the stench of mouldy Bread. <br> I call to complain I was put on hold for 5mins to speak to a manager then someone hangs up on me.<br> I call back get through to the manager and he tells me to walk back to return it &amp
