Germany: Tell the server the total including tip; don't leave it on the table
Do
When paying, tell the server the total you want to pay, tip included
For example, on a €24.80 bill, say "28"
Around 5%–10% is usual; for small bills, just round up
By card, choose a tip on the terminal, or pay the bill by card and tip in cash
Don’t
Don't leave the tip on the table
Don't feel bound by the terminal's preset percentages
Don't add 15%–20% as you might in the US
A tip is a voluntary thank-you: no one will reproach you for not tipping, and you can skip it for poor service. German restaurants generally don't add a separate service charge, and prices usually include tax.
France: Service is included in the price, so tipping is optional
Do
Look for "service compris" (service included) on the menu or bill
If service was good, you can leave a small tip (pourboire) as thanks
Round up to the nearest euro for coffee; leave €1–2 per person at ordinary restaurants
At upscale restaurants, leave 5%–10% for especially attentive service
Tip in cash where possible, so it is sure to reach your server
Don’t
Don't assume you must pay an extra service charge; it is already in the price
Don't wait for the bill to arrive on its own; signal when you are ready to pay
Tipping is entirely voluntary and not tipping is not rude; knowing what "service compris" means saves you from paying twice. French law requires restaurant prices to include service (commonly said to be about 15%), and meals are unhurried, so servers rarely bring the bill unasked.
UK: Tipping is optional, so check the bill for a service charge first
Do
Check whether the bill already includes a discretionary service charge, often 10%–12.5%
If there is none and service was good, leave around 10%
In cafés, rounding up is a welcome thank-you
If service was genuinely poor, you may politely ask to remove the service charge
Don’t
Don't tip again when a service charge is already on the bill
Don't feel obliged to tip for fast food, takeaway or drinks at the bar
Tipping is entirely voluntary and nobody will chase you for it, but tipping on top of a service charge means paying twice. Since 2024, UK law requires employers to pass all tips and service charges on to staff.
