Yeah, those people are f...ing crazy. But your biggest mistake was saying you were looking for work and you were staying with a friend. Work immigration is a big big deal over there. I got sent over there by my company without a work visa, had to enter the country twice within a matter of weeks. Major red flags. Got put into the "immigration questioning room", but I was prepared, long story short is I went the exact opposite route. I lied my ass off. Dressed like a rich freak, got an enormous amount of cash, hid my laptop and work stuff in a backpack (which they luckily never searched) , told them I was a trust fund baby there to see a girl. Gave them then name of a girl I had previously "had relations with" and made up an address for her on some street I had seen in Chiswick near her house and gave them her old work phone number which was the only number I had for her. Figured if they let me go, by the time they found me the job would be over and even if they did put me in Jail, that was probably better than going to the client. Only problem is I'm going through London this June, and my passport still has the "if this guy tries to come through here again" stamp in it. So I'm sure I'm going to catch holy hell again this time. Anyway, give the limey's hell.
