Two things have just suddenly struck me. Firstly, I'm wondering if he used cardboard boxes to rest on on the floor to keep the cold away from him. It's an old FA trick so he'd be aware of that. If so, it's not a giant leap from phone slipping from pocket, consciensous Corrie folding the cardboard up and shoving the lot (including phone) into the cardboard bin.
Secondly, if I'd have been in the nightclub I'd more than likely had have enough money in my pocket to share a taxi home with the lads or at least with someone I'd just met. That theory is all well and good until you get thrown out. That suggests more money than usual as it's an early bath for you sunshine. If he'd have secured a lift back prior to his kebab shop visit, I'd give serious consideration to 'eating' my remaining taxi fare in the form of a large supper too. What I'm eluding to is a suggestion that he made arrangements for a lift to (?) BEFORE he entered the kebab shop at 0100.
