Here below, you can watch a selection of funny sketches called "Bad Customer Service". Although the video (10:38) has subtitles and some of the humour is visual, the language is fast and there is no context for each of the clips, so, it is recommended for C1 students, who will find intersting words like: crummy, shady, to crawl, to lick, to spit, a puff adder, to trespass, mahogamy, to top, to stuff, to sharpen, the punch line, garbage, to shup up, highly strung, a dump, puke, proper, to unscrew, to scrape [it off], to drop in, to stick [your nose], to get my dander up, grotty, to get away with it, prawn, to faint [it], bastard, to care for [something], snob, stuck up, toffee-nosed, half-witted, upper-class.
If you want to watch Manuel's humorous misunderstandings, you can watch "Too Much Butter", "Manuel's in Charge", or "Manuel's Funniest Moments. Part 1". Happy Easter!
