074 "amongst other" usage

I gone in that shop a lot of time, but I don't like it, and amongst other things
the shopper is unpolite too. 
Is this sentence correct? And in this case is "amongst other things" correct?

I first heard amongst used when I went to live in England. To my ear it sounds quaint and very “British.” I especially like it in the expression “to put the cat amongst the pigeons.”

If there ever was a difference between the two words, it is lost now.

According to the OED, amongstis

[l]ess usual in the primary local sense than among, and, when so used, generally implying dispersion, intermixture, or shifting position.

But as Fowler said many years ago,

Such a distinction may be accepted on authority, but can hardly be made convincing by quotations even on the liberal scale of the OED.

He goes on to speculate that the reason that one or the other form hasn’t fallen out of use may be owing to “the unconscious desire for euphony or ease,” and illustrates his opinion this way:

few perhaps would say amongst strangers with among to hand,amongst us is easier to say than among us.

For American speakers of English, the question is irrelevant. Americans sayamong.

I hope that British speakers will continue to use amongst whenever they feel like it.
