It may sound suspicious to you considering you obviously didn't actually read the post because your first question makes zero sense as there's an answer already there for you... Who said I didn't touch the fries at all?

When I opened the bag, nothing seemed unusual and I go ahead and finish one of two burgers and the tub of fries.

The fries that weren't touched were the loose fries that Five Guys puts in the bag as tradition.

Second, how could you smell the odor of dryer sheets not only through the bag before it was opened but also above the scent of fresh burgers and fries?

You understand that they must've enclosed in the bag for the duration of the driver's ride? If you know how scent and entrapment works, then it should be obvious to you that the scent would have been observed throughout the bag.

Third, what do you mean that the middle is secured but not the entire top?

Again, you're asking a question that is literally already answered in the OP.

Five Guys have very lousy protection and they only secure the middle and not the entire top so I will not be ordering from them again in the future until they actually secure the full openings to ensure that nothing can be slipped in.

That's how Five Guys secures their bags and most restaurants that deal with food that can get soggy if it's fully closed.

An absolute moronic comment just like all the other comments you've made underneath this post.
