4 cases when you can not skip a lady forward

Usually she should be skipped forward. But not in these cases.

Doors
Push the revolving door yourself: it can be difficult. If this is the door of an elevator, bar, other dangerous room or it opens “from yourself”, go ahead.

Wine
You must taste wine first. Therefore, pour a little yourself and only then – the lady. (If there are pieces of cork in your glass, never mind.)

Taxi
You should be the first to sit in the back seat and move into the interior. Then the contact of the innermost places of the lady with the seat upholstery will be minimal.

Crowd
You have to go ahead and clear the way. In other cases, the lady should go to the right, and modestly look away when you study other ladies.
