Let's say someone orders some take away food by phone and are told that the bill will come to say $70.00.
They've already made the food (and again, told the price beforehand) thus would it be seen as unethical (even bullying) to haggle when picking up? Maybe you could say… 'how about' or 'would you' take $50.00 or some such discount as just one example. In many cases you'd have the upper hand as they've taken the time and made your selected order.
How might you expect a small restaurant or food service/take away to respond to this and would you see someone asking as rude, cheap or even bullying? Using more the example of the smaller establishment and not a huge chain such as Maccas' or KFC as of course systems will automatically disallow such.
who ever is negging you can feel however you wana feel but im speaking based on what ive seen, I've personally seen Indians haggle over food a few times now (last time was 2 months ago at a local kebab shop), not only were they haggling over the price they were also very annoying asking for more meat saying how it does not look full enough and I could see the person serving them getting frustrated. I've never seen any other race do that and hold up the line and ask for more meat without paying extra, let alone haggling over the price..
