Yeah, I tend to agree. I spent my working life traveling worldwide, and while I have certainly seen some unfair discrimination passing immigration in many different countries, more often than not the traveler does something to trigger the officers.
It's amazing how few problems I experienced personally over the years.
You are looking for something that defies reality.
Repeat after me. "Thailand Immigration Officers have broad discretion to make independent decisions which are rarely appealable."
You may get away with something for a while, but better to find a way to stay well within the rules. Expecting to get lucky every time will catch up with you.
No, it is simply a USA company and business model I am familiar with. But a quick google search confirms there are similar massive factories in SE Asia producing ice cream not only for their own brands, but smaller boutique brands as well.
For example, one company proclaims, "We create delicious ice cream. In order to produce quality ice cream, we use local fresh fruit as well as imported raw materials. Our unique Thai flavours include Durian, Mango, Ruammitr (mixed fruit) Coconut Cream, Milk Tea with Pearl and Pandan with Natade to name a few. We manufacture under our own house brand ‘Cremo’ and ‘Iberri’ for domestic and international markets, wholesale and retail. Chomthana also produces OEM (Original Equipment Manufacturing) or Private Label Ice Cream. Chomthana has 4 main ice cream production lines – extrusion, stick, cone and bulk ice cream. We also produce our own ice cream cones for wholesale and retail purchase."
You can get a spacious penthouse sea view condo with your own pool and probably even your own direct lift stop for less . Probably even a full-time maid and strong security.
Don’t sweat the details - utilities, etc. First, they’re simple to do, and second the booking agent will happily take care for you.
