The local one to me started out with this flying through it and the fellow toppled my 12 eggs so that they fell into my trolley and split all over my shopping.
The manager came along and I told him very calmly that it was both annoying and unnecessary.
I told him that some fruit had been bruised last week and now I had a shopping trolley half covered in smashed eggs.
It was a busy thursday morning and the place was busy.
I was deathly calm, but did say that I wasn't going to pay for bruised produce because his staff are under such pressure.
That is 10 years ago, and I have never had a problem again.
I find the staff in Aldi overwhelmingly great.
Someone flinging stuff at super speed is very annoying.
I certainly wouldn't tolerate it.
