Dress smartly dressed, be polite, simply ask to see the manager and say " Hello, I would appreciate it if you would look at my CV." When they say "Yes of course" Say "Thank you" and leave.
Give it 2-3 days then phone, ask for the manager and say "Hello, I handed my CV to you on ...day and was wondering if (a.) you would like to interview me (or if not) (b.) any feedback?"
You need to know if your CV is well written and well presented.
