I suppose we should be grateful they didn’t say, “Have a butcher’s.”
Have a biscuit — take a biscuit?
Any signs of “have a shufti” or “have a butcher’s” yet?
Or “have a vada”?
How bona to vada your jolly old eek.
To quote Julian and Sandy.
Fantabulosa, my dear homey or palone.
“Take a look” is BrE, too, by the way.
I’ve used “have a dekho” – in US context, but in conversation with co-workers from India and Pakistan. You often see “have a dekho” or “take a dekho” in older books, especially with military context, but the spelling by British writers was usually “dekko” rather than the more “correct” dekho.
Dekko is very popular in Oz.
Also “have or take a gander”.
