Some factors that you may want to consider when deciding whether or not to tip include:
- The level of service that you received. Were the technicians courteous, professional, and helpful?
- The cost of the service. Did you feel that you got a good value for your money?
- Your own financial situation. Do you have the extra money to spare?
If you do decide to tip, the amount that you give is also up to you. A common rule of thumb is to give around 10-20% of the total cost of the service. However, you may want to give more or less depending on the factors listed above.
If you are not sure whether or not to tip, you can always ask the technician. Most technicians will be happy to answer your question and provide you with guidance on how much to tip.
