Are you taking the P**s!

So some guy came to the bar and asked for 4 drinks, I poured the drinks and placed them on the bar for him. He had his card in his hand so I when to grab my card machine and he asked me for a tray, I passed him the tray then started to enter his amount in the card machine. He then shouted at the top of his voice "Are you taking the piss!" I say excuse me? He said do you expect me to pick them drinks up and place them onto that tray! I said you just asked me for a tray so I have just passed you one. He then began you swear and say why should he pay £23 for drinks and put them on a tray and how it's my job! I mean if he didn't shout at me and gave me a few more minutes I would of done! I don't get how they think they can speak to us like that! in the end he kept swearing at me so I took his drinks off him and asked him to leave! #Arse
