How likely is it that immigration will require my mother to show 20,000 baht in cash when entering Thailand for the first time?

A user inquired about the likelihood of their mother, a first-time visitor to Thailand, being asked to show 20,000 baht (or equivalent) in cash at immigration. Most responses indicated that it is extremely unlikely she will be asked for proof of funds, especially since she has a hotel booking and an exit flight itinerary. Some comments suggested that having a buffer, such as around $650-$700, would be prudent as immigration may use a differing exchange rate. Overall, the consensus was that newcomers to Thailand generally face minimal scrutiny regarding cash requirements.
