A police officer canceled her McDonald's drive-thru order ... because she feared employees were messing with her food -- so she gave a tearful plea to cut cops some slack ... and show some appreciation.
The officer explains in her selfie vid she just got off a long shift and is very hungry, and all she wants is her McMuffin meal with a coffee ... but it's taking a while ... and she seems to suspect something fishy's going on.
She gives the play-by-play of her order delay, and after finally getting her coffee but still no food, she says she tells the Mickey D's employee to keep it ... because she's too nervous now to eat it.
The cop then breaks down, saying she's never been this anxious in 15 years on the job to pick up a to-go order she can't see being made. She adds ... "I don't know what's going on with people nowadays," and pleads for everyone to give cops a break.
Not just a break ... but also to tell them thank you, because she's not hearing that enough lately.
Of course, this officer's meltdown comes on the heels of 3 NYPD officers who feared they were poisoned by shakes from Shake Shack ... but an investigation proved that wasn't the case.
