...how does it affect your opinion of the place and does it impact whether or not you give them your business?

For example, coffee shops that use "expresso" instead of "espresso." 10-15 years ago I could maybe understand, but these days you should really know the product you are selling. The coffee shop near my office, where for years I would get my morning cappuccino, went under new ownership last year. The new owners renamed it "..... Expresso Bar" and there was a marked decrease in quality. I haven't been going there for a while now.

The other example that has most recently affected me has been while looking at wedding facilities. Often as part of the packet places will send their full menu offerings. When I look at the menus and see glaring errors (e.g. chicken francese) the place is immediately off of the list. If they can't get common food spellings right, what does that say about the quality?

Thoughts, opinions, experiences?
