For fast food:
1. If there's a long line, there is NO excuse for not knowing what you want by the time you're being served. Don't hold up the line for ages because you're an idiot who can't make up your mind.
2. Be nice to your server. It is the difference between getting free sauces, extra napkins and hot chips, as opposed to me scraping the chip dump for all the old ones that have been there for a while.
3. If you're at Oporto, don't order a fucking bondi burger "without the chilli". If you can't read the menu and you're rude about it, I will pointedly explain the difference and make you look dumb in front of your gf.
4. I hate this, for couples: if I look you in the eye and ask politely what drink you'd like, don't whisper it do your partner and make him/her to tell me. I asked you, dammit!
5. Don't slap your money down on the counter when my hand is outstretched. It's really rude. Would I do the same thing with your change?
6. If I tell you upfront there will be a 5 minute wait while your food is cooked fresh and ask if that's OK, you have the choice to walk away and eat somewhere else if this is a major inconvenience for you. Don't roll your eyes and glare at me the whole time because there is nothing I can do about it and I've given you fair warning.
Pharmacy:
1. When I ask politely "if you've got your medicare card on you..." it's not because I think you're trying to cheat the system. I don't care if you've "been coming here for ages, I should be on the computers" but IT'S THE LAW. It's my job to check and there are signs all over the counter saying this. Doctors sometimes make mistakes, people get new cards... and then who'd be the first one to bitch about paying more because your card number came up wrong?
2. Do not get aggressive with me because the pharmacist won't sell you whatever drug you're after.
3. Please don't completely muck up all the shelves and sunglasses stands. If you do, try and at least look apologetic about it?
4. Unless you buy something big/heavy, most pharmacies will put your purchase in a paper bag. When I ask "would you like a bag for that?", it's almost always referring to a paper bag. So if you would like a plastic, no worries, just please ask BEFORE I've taped up your pills and scripts in a paper bag. The first few times, no biggie. But when you're a regular customer and this happens every time, it gets annoying.
5. If there's just me and the owner there and the doors are down, we're closed and only let you in because of his goodwill. Once you've paid, don't hang around trying on sunglasses because we're CLOSED. Go home so I can do the same! I don't get paid to hang around while you do.
Ahh.. writing that brought up all these memories of crappy customers. Hopefully everyone who reads this thread will recognise and lose a few of their own bad habits as customers.
