This is one of our personal bugbears, the idea that women shouldn't offer to help carry or lift things. Pachter says the new guideline is that everyone, regardless of gender, should offer to carry packages.
If someone's struggling, sure, but why is it assumed a woman isn't able to clothe herself correctly?
"The new guideline is whoever gets to the door first, should open it and hold it for the person behind him or her." Quite sensible, really.
This is just plain unnecessary.
Barbara states that whoever the guest is, they should be the ones to order first. So if you've called the dinner, allow your invitee to order.
There are so many issues surrounding this. But as you guessed it, Pachter says the person who proposed the meal should pay, regardless of gender. We're more of the opinion that you split, but that's just us.
This is just horribly old fashioned. If you don't know the gender of the person, use something gender neutral such as 'Dear customer,' or 'Dear company representative.' 'To whom it may concern sometimes also works.'
Whether you're male or female, you still need to shake hands. "It's a business greeting, Pachter confirms."
