Pathetic Contaminated Food

My btother ordered food on Saturday 22/10/2022. It was a a sausage Mc****in and hash brown. I was still in bed when the food arrived and he went back to his room after he received it. We Normally check our food but was tired. I got up refreshed and ate my breakfast. However when my bro decides to heat his food there is a bite mark that is on his Mc****in. Is McDonald's now giving us left overs from other customers. We ordered via uber eats,but thd driver can not be blamed due to the fact that all bags have a tape as a seal. Drivers would get caught if the seal broke. So now we have this saliva exchange on the bun. Don't know what other contamination is happening at the back. We could not get no assistance from the store or uber eats. Big franchises don't care about all this. People will just look at this review and ignore it till it happens to them or someone important. To hell with this filthy service... I rather support local.
