Great tips, thanks! I'll try to read up a bit more about the places we visit. I usually have a little spiel about the prohibition and how it relates to Montreal but I keep it short since most people on my tour are Americans. Didn't know you used to run tours like this. You really did a lot of different things eh!?
We've been running the tour for a while, so the bartenders know us already and are great sports about it. If they can, they try to keep an open seated spot for us :) However, to get a "specialty" drink or even a smaller version of a drink, they can't really do much about it. I need to speak to a manager for that. I'm going to ask the bartenders tonight if they would consider splitting a cocktail into 7 "shots". This way, we'd be paying for 4 drinks (we visit 4 bars) instead of 7 and the people would get a taste of the signature drink at every place. It's more work for them, but even if we tip generously we come up on top expense-wise.
You have any wild stories from your tour guide days? Where was that? I'm guessing somewhere in the UK?
