All depends on the woman. Everyone is different. I will give you a true example (same age difference) man takes out his thai girlfriend for dinner to a restaurant (very pleasant, tables by the river), the bill came to just over 400 baht, the lady turned to the man in all honesty and said I am expensive to take out. Example 2, the man wanted to do something a little special for his birthday, he suggested staying at a nice hotel with dinner, the same lady as above said I am low class, I would feel more comfortable staying at a cheaper hotel
