pronunciation advice

[MacLowlife]

Here's another one then. As someone who enjoys an occasional dram of whisky, it's often bothered me to hear bartenders pronounce the "ch" in Glenfiddich as you would in "church". But I've always thought the proper pronunciation was with a hard "ch" like I've just learned from this thread is the incorrect way to pronounce "loch". So am I to understand that it is in fact similar to the correct pronunciation of "loch"? And what about Sarah McLaughlin? Is her name pronounced differently because it's McLaughlin instead of MacLaughlin? Sorry if I sound ignorant, but I'm honestly curious, not trying to offend anyone.

I am not sure about Sarah, but I believe Glenfiddich is pronounced GLEN-LIV-IT.
