Worm in my burger

I purchased 2 grand chicken spicy meals and a happy meal from McDonald's bracken city at 20:30

When I got home and decided to have my meal, to my surprise as I was eating there was an extra in my burger.... A WORM!!

HOW DISGUSTING

I called the store and the manager did not want to take my call until I mentioned I will report it to head office. She then called me back 10 mins later and says that I must bring back my meals (obviously I won't be compensated for my fuel to go back to the store). So she can replace it.

According to store manager, they don't check the lettuce before putting on the burger, they just take it and place it on.

She asked me to bring it back any day even the next day so she can replace it.... But hello, I bought it for supper and not to eat the next day... How ridiculous
