Any answers I quote are those of the setter. I did not necessarily get them!
Q17,We ordered these historical and legendary figures as follows — Wenceslas (charitable giving, 925?), Bishop Hatto (eaten by mice, 970), Erik the Red (discovered Greenland, 982), Brian Boru (made High King, 1002), Macbeth (became King, 1040), Godiva (rode naked, 1050?), William the Conqueror (won at Hastings, 1066), Hereward (led rebellion, 1070), El Cid (took Valencia, 1094), Omar Khayyam (wrote Rubaiyat, 1110?), Cadfael (solved murders, 1140?), Prester John (wrote letter, 1165), Robin Hood (ruled Sherwood, 1194), Genghis Khan (captured Peking, 1215), Llywellyn (ruled all Wales, 1254), Marco Polo (visited China, 1271), Pied Piper (freed Hamelin of rats, 1284), William Tell (resisted Austrians, 1307), Geoffrey Chaucer (wrote Canterbury Tales, 1388), Dick Whittington (became Lord Mayor, 1397). Most readers agreed with this, but other orders were given full credit if convincingly argued.


Guest: yes, 4, Ground floor.., perfumery, stationery and leather goods, wigs and haberdashery, kitchenware and food. First floor.., telephones, gents' ready-made suits, shirts, socks, ties, hats, underwear and shoes, according to the Are You Being Served? signature tune         

okthen: that's a start to the answer of No 20, which should help others by making the connection clear.

6,e anyone?
