Mr. Donaldson gives us four theme answers that are variations of things you'd gladly hear your companion say at a bar - although all but one of them (DRINKSONME) could work in a restaurant setting as well. My favorite is the two-parter YOURMONEYS NOGOODHERE. I'll drink to that!
This topical theme doesn't do much damage to the surrounding grid. I enjoyed CRUSH, WRY, NCC (of course), NOODGES (vocabulary-wise), CLOD, and LOCUTION. And, I'm always happy to see a reference to the NETHerlands - even in abbreviated form.
There was also some solid clue/answer pairs:
Big farm workers (OXEN) - nice twist
Country whose name can also be a full sentence (IRAN) - pleasing
They might make lids difficult to close (STYES) - nice misdirection, but I wasn't fooled.
Tiny opening? (MICRO) - ha!
Change of locks? (NEWDO) - fun.
Some of the plurals like DALIS and KENS, and to a lesser extent HEYS, BORERS, and RAHS, I found a little ODDS, but maybe Mr. Donaldson's policy is 'the MOHS the merrier'. :)
