We were lucky enough to be at a roadside market (again!) when all of a sudden a truck with the loudest, public address system pulled in to the market and started playing music. The volume had been set so loud that the music was 'clipping' and it was hard to make out the cacophony of noise as music. In between tracks, a disembodied voice would come on in Thai, extolling something or other.
This market was set off from the road in a large inverted "U" shape with the two tops of the "U" facing the road. The market itself was about 100 metres in length and about 50 metres in width.
I was standing near the back of the market, furthest from the road and as I looked down toward the truck, I saw fifty to sixty Buddhist Monks arriving in all sorts of vehicles: tip trucks, mini-vans, tray trucks, everything but a bus.
The Monks formed an orderly queue and, with begging bowls in hand, began to file silently past the market stalls where the stall keepers would each place an item of food in some of the bowls. This is the way the Monks feed themselves, through the generosity of the Thai people.
