Dittany "the point isn't whether they were tempted or not. The point is about putting yourself in situations where temptation might come up."
Well, if no-one fancies anyone in the group, then there will be no temptation whatever the situation.
To use Chamomile's point - IF I was on a diet, I probably would avoid lingering in front of Patisserie Valeri's window because almost everything in there would be whispering 'eat me...buy me' and eventually I would rush in and throw £3 down on the counter for a slice of Paris-brest.
On the other hand if was passing Robert Dyas, I could safely throw myself in amongst the display and have a go on the test model of a percussion drill because none of it would interest me whatsoever and i wouldn't buy it!
Or to be more logical and analogous, if I were on a diet and passed a sushi restaurant I could linger and admire the decor with no risk of temptation at all because sushi just doesn't tempt me. At All.
If we can assume that the men from the pub and Harman and her friends were all the equivalent of the sushi to each other, then there would be no risk, whatever the situation.
And even if they were great big coffee eclairs, I understand that some people manage to resist. Though my own record with confectionary and men is not unblemished in this resepct.
