Post
Post offices are usually open from 8 am to 12 noon and 2 pm to 5 pm on weekdays, although some branches in shopping centres often open the same hours as the shopping centres, and this includes late night shopping (usually Thursdays). On Saturdays, post offices in large cities are open from 8.30 am till 12 noon, but don’t count on it in villages.
