Minus two stars for charging a same-day cancellation fee (10 Euros per person) - imho unacceptable for a quite regular/everyday place like this on any day of the week, but in particular on a Tuesday evening.
And taking off another star (two if I could) for the original behavior of the owner in replying to customer reviews.
Your example with the hotel is a poor one: for a hotel, filling a room for the night after a same-day cancellation is much less likely than for a restaurant to fill a table on a busy night. In fact, your restaurant would cash in twice when charging a cancellation fee of 20 Euros a table AND then filling the table with walk-ins. And on a non-busy day, the restaurant would not lose any revenue anyway by not filling the table - so your rationale makes no sense either. Actually, your policy can deter people like me (who cannot fully plan the time the get off work) from even coming when reservations come with the risk of fees. So you lose turnover and customers - congrats!
And to your question - yes, I know your place very well, have been there many times. I will refrain from frequenting it again in the foreseeable future. My thanks to your friendly team (of which you seem to hire too few, as service is sometimes quite slow).
