Although you would be unlikely to ask that fit lass in Boots for a good ol' pack of 3 'Protections', the word may be used in a context as thus...
Scene 1 Act 1 - Night. ext. - Behind bottle bank near Whetherspoons -
Fit lass - "Do you have any..protection?"
You - "One Union Jack cheese & onion tickler coming up!/ Not as such, but there's a half empty packet of Golden Wonder down there, would that do?" (delete as appropriate)
