How slowly can you eat at McDonalds?

Yes, that's right.  How slowly can you eat at McDonalds. A few of you may have seen my outcry on facebook, for those who haven't; here is is in all it's glory:
August: is there electricity. Oh yeah, it's on and everything. Today: the electric has been cut off. So I ring EDF, earliest we can connect you is Thursday. I am living without electric for a week. Comment dire 'rage' en Français? On the upside, successfully sorted out a bank account, cheap pay as you go phone, and opened a electricity contract. Reasonably successful first day.

So, a quick trip to McDonalds which is luckily just round the corner. They have plugs! Excellent, I can charge my laptop there, and use it at my flat. The area is covered my Orange wifi, so until I set up my actual internet account, I've bought 10h of internet access. Excellent! So the question is, how slowly can I eat at McDonalds to charge my laptop? I'm hoping for 45 minutes tonight. 

So, I'm here. What have I done so far? 
-Open bank account: check
-Electricity: Will be connected on Thursday, so bought battery powered lights.
-Got a French phone (My UK phone will still be connected though, so text me or whatever if you want).
-Internet: In progress...
-Transport: In progress..

Oh, but I've found the most amazing Pizzaria about 10 minutes walk, some of the best pizza's i've ever tasted. Make sure you come and visit guys! 

Room tour, well that will probably be tomorrow. Things are looking good right now.
