English.... this foreign language

Just came back from interacting with a travel agent. In the past, whenever I've dealt with travel agents, they have always read the itinerary back to me (or printed it out for my perusal) before taking that final step of issuing the ticket.

I made a tentative booking early last week, emailed a query about the chances of getting to travel on another date later on in the week, but never once said "issue me the ticket with the queried date". Travel agent takes dates from my query and puts them as actual travel dates, and since the pay order has come through from work, goes ahead and issues the ticket without confirming with me! Then she wants me to pay to change it back to the original dates.

It took some doing (staring each other down, her trying to make it seem impossible to undo, me sticking to my guns), but we were finally able to agree (with the help of her boss) that she change it back to the original (non-query) dates. I didn't feel too good about going toe-to-toe with her, but the thought of parting with money to fix something I had not ok'd was just as uncomfortable. May still cough up money to change dates later, but that'll be because I choose to change, not because of miscommunication. This english language... and assumptions... (sigh).
