You missed out pretending to be a foreign tourist. The answer is it depends on mood and circumstances.
Did put 20p in to the parking ticket machine moments earlier. Hard to know whether things are genuine or not
Tesco around 9pm, all sandwiches reduced to 20p, know somebody who goes every night to get her old man's and kids lunches for the next day.
That's what local crack heads do aint it? Stand outside asking everyone for 20p and once they have enough pop off to their local dealer and pick up a 10 lick lol. I just walk on
If I was asked for 20p and he was dressed in a Ralph Lauren three piece suit with matching tie and shoes I'd probably look at him cock-eyed, but if he was sitting at the side of the pavement with a sad looking dog, dressed in rags asking, then I'd offer to buy him the sandwich and wait for the predictable 'i just want the money, man', and then walk away feeling disappointed with human nature and that I almost let myself be suckered, again. I feel you need an extra choice answer to your question.
