In Europe tipping is not mandatory and I like it this way. I don't get how you can tip 20% of your bill to a waiter. Imagine you get more expensive food and drinks and leave 200 EUR at the restaurant, compared to someone who lives just 20. Why should you give a much bigger tip if you're letting the whole restaurant make more money?
I usually leave a tip at the restaurant but it's never a % of the bill. If I spend 20 EUR I might tip 3 EUR, but if I spend 100 I'll still tip not more than 5 EUR. Where I come from a tip is meant for a bartender or a waiter to get a drink on my tab. If a beer costs 3 EUR at a pub, that's what I'm going to tip, regardless of the money I spend there. When I go with a few friends each of us leaves 3 EUR so the guy get beers from all of us.
bottomline, it is all up to you. but if you want to read a lil bit of culture for every country you visited, you may do so. it will give you insights the variation of culture from one place to another and why they have such traditions. but tipping has no defined laws and regulation. if you feel you're up to it, then give it. but if it is not, like if it is already your last money, then don't force yourself. you won't be jailed because you're not tipping somebody else's service.
Yes, i do also have those kind of feels where there are times which i do love to tip when i do get satisfaction on someones service even though to think that they are being paid or have salary but at least im much aware
on how low these people been earning on monthly basis which is something that we do have in reality but its not that compulsory on giving up tips.Its optional and you arent obliged on doing so.
This is why you should really not make yourself get stressed and i dont even know that why this certain topic needs to be discussed considering this action is on self will.
Im surprised that there are even workers who are really that expecting for some tip which it is a bit too much i would say.
