I had a run-in with the barstewards back in October. Was working in the grounds of an old folks home and had to jump over a fence into a neighbouring garden to retrieve some tree waste.
Jumped over, feet first into a woodpile/wasps nest.
Noticed one "oh, look a wasp" noticed another "that's wierd, two wasps" then suddenly the air was filled. Was back over the fence in about 0.5 seconds, sprinted across the lawn being pursued whilst simultaneously getting stung. They must deliberately seek out ways to get inside your clothes, as I had one in my hard hat, one up my trouser leg and one in my boot! I rapidly flung all my gear off, leaving a trail of clothes behind me until I was left hopping about and slapping myself, wearing just my pants and one sock!
On the lawn of an old folks home. In full view of the residents.
Got away with only being stung five times, my mate had to pull the arse-end of a dead wasp out of my head, (still got an annoying 'spot' where that happened) and the one just inside my boot took a few days to die down as the boot was irritating it constantly.
Where I'd thrown down my hoodie on the grass, I went to retrieve it only to find a 'sentry' wasp sitting on top, waiting for me. Left my top where it was for the rest of the afternoon, came back to it 2 hours later and he was still there! So I left it.
My mate thought I was being a ponce so went and picked it up for me and got briefly buzzed by the same wasp. After a few seconds he thought that it had gone, as did I, until we got into the truck to go home and matey was about to drive off, when he leapt from the cab and did the same 'trousers off' dance routine on the lawn. It had gone up his leg when he went to get my hoodie.
