I work as a waitress, and I know how upset people can get over the tiniest of details. For example, I once had a table walk out on the bill because we ran out of oil and vinegar. We never know how someone's day is going. If only we could have the ability to know what one another is thinking.
Occasionally I get upset with something that happens with my order, but I know I'll be placing another order probably the next day or the day after, and I know to just put it in the comments section and it is taken care of.
.... happens, people aren't perfect, but I know I won't find 80+ flavors anywhere else. I know I won't find a warrantee like this anywhere else. You always get a dud every once in awhile, this is a fairly new technology, it isn't completely solid yet. But I understand people'e frustrations, when we were smoking cigarettes, we never got one or two cigs that wouldn't LIGHT. Lol.
