Senior citizens are highly revered in Thai society and are treated with deference and respect, which comes as a pleasant surprise to many first-time Western visitors. Unfortunately, this deference does not stretch to offering the kind of discounts on transport and admission fees that you might be used to back home. There are exceptions, however, and it's always worth asking politely if there are preferable rates for senior citizens, as Thais take pride in accommodating their guests' wishes.
