Hotel staff will expect a tip for the carrying of luggage and other small errands. Aside from the most expensive hotels, the wages of hotel personnel in Nepal are next to nothing, so the staff, are dependent on tips to make ends meet. If you are going to stay somewhere for a couple of days, it is a good idea to offer a tip straight away, as this will increase the speed and attentiveness of your service. About 10 rupees is a reasonable guideline. Taxi and motorised rickshaw drivers will not expect a tip. Neither will bicycle rickshaw drivers, although these poorly-paid fellows can be made very happy by a couple of extra rupees for their service. In expensive restaurants there is a service charge, while tips are non-existent in some of the cheaper places.
Porters and guides will expect a tip. We recommend 2 Euros per porter per day as a guideline. For the driver, 100 rupees per person per day is a good guideline for a tip. This of course is provided they have done their work well. The tour leader (and a possible "assistant guide" during any trek) also expects a tip, if she/he has done well. Shoestring pays the tour leaders a wage that is on par with that of most adventure travel companies, but it is still low. Our guideline is €1 per passenger per day.
