Lounging over a counter is ill-bred.
Putting your elbows on a counter is rude.
Pushing aside another person is an act of ill-breeding.
You must never take hold of a piece of goods another person is examining. Wait until it is replaced upon the counter, when you are at liberty to take it up.
Stage asides or whispering in a store are rude.
It is rude to interrupt friends you may meet in a store, to ask their attention to your purchases, before they have finished making their own. It is as rude to offer your opinion, unasked, upon their judgment or taste in selection of goods.
A gentleman walking with two ladies may offer an arm to each of them, and they may thus sandwich him if they wish; but under no circumstances may a lady take the arms of gentlemen at each side of her.
If a gentleman is walking with two ladies in a rain-storm, and there is but one umbrella, he should give it to his companions and walk outside. Nothing can be more absurd than to see a gentleman walking between two ladies holding an umbrella, which perfectly protects himself, and sends little streams of water from every point on the dresses of the ladies he is supposed to be sheltering.
It is in bad taste to talk of personal matters in the street, or to call loudly the names of persons you may mention. It is impossible to say who may be near to you. To discuss friends by name in a public conveyance of any kind is rude in the extreme.
If you meet a friend with whom you wish to shake hands, never put out your own until you are quite near, as nothing looks more awkward than hands extended to grasp each other two or three yards apart.
