Tipping in Qatar

I think I’ve been over-tipping in Qatar But recently I started noticing it adds up fast, especially with daily stuff like Talabat. so I did some research and came up with this:

1. WOQOD washers (initial wash)
   People: sometimes
   Suggested: optional 5 QR

2. WOQOD cleaners (final drying/cleaning)
   People: more common
   Suggested: 5 QR if they do a good job

3. Barbers
   People: yes
   Suggested: 5–10 QR (but not every time)

4. Delivery drivers (daily orders)
   People: sometimes
   Suggested: 5 QR (max 10, not every order)

5. Restaurant servers (normal)
   People: rare
   Suggested: optional (0–5 QR)

6. Mid-range restaurants
   People: sometimes
   Suggested: 5–10 QR

7. Fancy restaurants
   People: yes (depending if service charge included)
   Suggested: up to ~10%

8. Uber drivers
   People: rare
   Suggested: optional (0–5 QR)

Curious what you guys think?

Also Do you tip daily services or just occasionally?
