This was a pleasant boat trip around the Inner Harbour, and the guide provided some interesting information.
However, the two people at the ticket booth were unhelpful and not very friendly. I had pre-booked tickets using Viator and had to exchange the voucher for tickets at the booth. First the guy couldn't find my tickets, despite my name being on his list, and eventually had to re-print them, but the dialogue between him and his female colleague about whose fault it was, was anything but friendly, and I almost felt it was my fault he couldn't find them. Next I asked him which boat it was as their were two moored near the booth and he told me the wrong one, luckily the one he told me wasn't going anywhere that afternoon ! What surprised me was there was none of the normal American polite and friendly banter or apology while he was searching for the tickets and not so much of a Hello, Thanks, Sorry, Have a nice trip.
The tour itself was pleasant though.
