Serious question?
Millions (of Thais) buy at Lotus, Lotus Express etc.
It can be empty mid to end month when pockets are empty.
And of course it depends on the local competition.
Since a while it's been swallowed by the mega tycoon clan (7/11, Makro, Lotus etc.).
And what I observe here is a cleanup of the selection.
Throwing out low sales stuff.
Among that a lot of "farang"/exotic stuff.
Much to my displeasure. Gets more and more unattractive.
BigC Khon Kaen often dead as a dodo.
And selection for "us" very poor.
Makro is never that empty as Lotus or BigC.
