ATMs are widely available, except at border crossings with Jordan and Egypt. Credit cards almost universally accepted.
Tipping is not expected in most circumstances, but is increasingly common.
Restaurants Waiters and waitresses will expect a tip, 10-15% is fair.
Pubs Usually have tip jars on the bar; 10-15% of your bill is fair.
Guides It's always good to tip guides. Organise a whip around among other guests; 10-20NIS each is probably fair.
Hotels 10NIS to 20NIS a night for housekeeping is a nice touch.
Taxis Will not expect tips, but you can round up the price of the fare.
