I've approached A/G fields and asked for 'information' only to be given precise joining instructions. e.g.
A/C "XXX Radio, G-AB inbound, five miles north, 2000 ft. request airfield information"
A/G "G-AB etc etc etc etc join left base for 27 etc etc
My response is always:
A/C "sorry, is that XXX tower?"
A/G "No, this is XX radio"
A/C "Well, in that case, my intentions are.... etc etc etc"
Naughty, but.................
