Stale and old food, coupled with bad service and rude behaviour

Today I walked into Wimpy and ordered some calamari, chips and a salad and was sold stale and old calamari which was chewy and rubbery, I could literally pull tough bits of the calamari with my hands and set aside, initially I thought it was just one piece but realised after eating for more pieces it was all the same.. I then asked the colored lady whom I thought was the manager to take back the calamari..

Minutes later a guy who was not wearing a mask from the kitchen or was it a manager came through to tell me that's how Calamari is.. And there's nothing they can do in essence he was compelling me to eat the stale and overcooked calamari, I explained to him that I eat seafood and I know what fresh seafood taste like and this was not it.. And he told me all their calamari was like that I told them I had no problem with walking away and paying for what I ate.

I asked for a bill over 15 minutes later I was still sitting there until I asked the waiter how long do I need to wait to get my bill, I indicated that I am not paying for the stale calamari I didn't eat.. Still 10 minutes passed until I walked to the Tolland demanded my bill, the calamari was added I told them I'm not paying that..

Minutes later the manager appeared and I was told they were checking the video of how much of the calamari I had eaten, in essence to force me to try and pay for the ******* food they concluded that they can't make me a new portion as they were all like that.. Eventually they agreed with me just paying for the sides and the juice..

I was highly disregarded and disrespected when they attempted to get me to eat the calamari by someone who's never eaten calamari with him telling me that's how it was.. I had to fight to get a bill even walking up to the till because the waiters who give terrible terrible service couldnt be bothered
