I also have lived in numerous countries, some that I could not have afforded without a corporate package that covered the rent, car, and a cost of living adjustment. I adjusted to the local norms. In some countries there was no tipping—it was considered an insult. In others there was a yearly ‘tip’ in the form of a significant financial gift. In others, the wedding guest needed to contact the venue to ensure that the wedding gift, always money, covered at least the cost of your part of the party.
