Huh. You'd think a gratuity would already be assessed.
It would, but the people who would post to this sort of thing are also the sort of people that expect you to tip on top of that.
Since the quote described the office/workspace, I figured that was for a delivery order.
I hated bad tippers when I worked as a waitress, but only because I depended on tips to make rent and bills. It wasn't really the people I hated, but the system.
It's too ingrained to change unless restaurant owners or governments forced the issue (I doubt they will), but I really don't think the system in North America works very well anymore. People are too dependant on tips since wages of servers are artificially depressed (exceptions to allow below-minimum wage for servers, etc.), so the average person won't stiff people them under any but the worst circumstances, which I think actually undermines the whole idea. Ultimately, I'd prefer to see fixed bills, including tip, with real cash tipping being much rarer and only in cases of exceptional service.
Tipping here is now in this semi-official no-man's land where we acknowledge that it exists but don't track it comprehensively, which is really awkward and probably the worst of both worlds. I'd rather we either monitor it in full and completely include it in income (the eventual result of which is mandatory tips on all bills by default) or cease acknowledging it in any official way (which would mean removing the exemption that allows servers to be underpaid). Right now we're starting to get bullshit like IRS (or Canada Revenue) auditing the tax returns of servers, with no documentation, no obligation on the part of the employer, and other ridiculous nonsense.
