Most Muslim shop owners close early or do not open on Friday, and Christians follow similar rules on Sunday.

Museums are generally open every day except Tuesday, but opening hours sometimes vary. To be safe, bring a multi-purpose adapter.
American equipment requires both an adaptor and a transformer.
Most varieties of adaptors and transformers are readily available in electrical shops throughout Jordan. Electrical current in Jordan is reliable and uninterrupted.

Taxi drivers are generally not tipped, but it is customary to pay the nearest round figure to the price on the meter. It may be difficult to get change for a large bill, so carry plenty of small denominations and coins for taxis.
