Depressing lunch

So there I went with my Dutch friends and my brand new friend out for a nice lunch on a nice terrace. Every thing went wrong I don't know how he does it but he realy makes every body depressive. Look at my friend they are on holidays normaly they smile but not now actualy they went back to holand after lunch..... Coulden't take it any more. Aswell as the normaly o so very nice waitress imediately turned depressive and there for we missed out on some salades and other food. We were asked to leave because after have an hour every body went mental. I realy don't know what to do and have to come up with a solution soon. Maybe you can firts help me out by finding a name for the thing. By the way I already miss you guys and hope you will be hapier in Holand.
