Was walking dog today on the grounds of a housing estate (nothing fancy, but the green areas are managed privately, yet it is public accessible land and permitted for all dog walking nontheless) and the maintenance operative said, 'We've had some incidents here with people not picking up and I take their photo and get them prosecuted, so can I check do you carry bags?' Me, 'Yes, definitely, gives the rest of us a bad name, no excuse!' smile and nod. Him, after a long pause... 'Well, can I actually see them then?' 'Er...ok', show bags. Now, though, I'm feeling peeved that he didn't trust my word and at his rather bullish attitude (also thinking he was emboldened by the fact of me being a woman and younger than him).. Should I take it on the chin, or was he being OTT?
