is it that bad to not order anything more? i mean you might come off as a cheapskate but i assume ppl use it as a place to work/study but if anything it'd be less work for the cashier as opposed to it being a super busy day and one person taking up a seat from like a hundred others or so, tho the 'ordering a single coffee and staying for hours' is a negative meme/stereotype? But not like it's like they're there to mooch off supplies or so, like how some signs have 'bathrooms for paying customers only'
Versus him taking up multiple spaces or so , i'd think working ppl would complain more about difficult customers than cheapskate ones
