I have never seen the basic street foods inflate by 1%. Noodles, chicken rice etc always inflate by at least 5 baht. Anyone who occassionally eats from a street vendor or restaurant has seen 10%, to 25% increases.
Generally even the smallest increase at Big C, Lotus's or 7/11 equate to 10%.
There are official inflation numbers and then there is reality.🙃🙃
